The mainshaft bearing on a 65 ,I assume it's a 65 ,is a standard bearing obtainable from your local bearing stockist as are all the seals ,replace the seal springs with stainless ones.Take the bearing with you to match they will just need the numbers.By a reverse thruster I assume you mean a bucket,this is more difficult. It is a non wearing part ,so I assume it is lost or broken if it is broken and the LM25 is not too dezictified it may weld if not I would try advertising for a secondhand one
VT are a very large concern with correspondingly large overheads and in my experience prices to match,they can sometimesbe very helpful with information though.

Good to see you on the beach the other day. Nice to have a fellow Dateline-er to chat to.

If you still have the drawings from Vosper any chance you could email me them over?? After what you said about the bearing, when you did yours was it easy to remove the old bearing or did it need to be pressed out and back in. Hoping to do mine without removing the engine if possible and also without too much dismantling of the jet unit!!!

I'll perhaps see you on the beach this weekend if the weather stays like this;)

Hello Gents,

I am as well looking for parts for a PP Jet. I have a PP90 I think, SN 900761
and manufactured at PP Jets Bury Street, Edmunds, Suffolk, England around 1987.

A photo is attached. I need an impeller and bucket. Basically what is missing from the photo.

Appreciate any assistance.

windydave13

I can't help you on identifying it, but i've just managed to get a set of drawings and instructions from a chap called Brent Voce (T +44 2392 53 9739 ) at NAIAD DYNAMICS UK LIMITED, who are part of the Vosper group.
He was really helpful and very knowledgable. I'd highly recomend giving him a shout as if it's anything like the drawings he gave me, it will have all the part numbers for the parts you're looking for.

Hope it helps

Regards

Dave

Hi Kcmd if you look back through my posts you will find comprehensive instructions as to how to do this, it is archived under powerboats ,13 August 2010. If you can't find these post again .That greasecup you are referring to is a DU bush and best run in EP90.
Garybull if you post pictures of your jet I will tell you if it is a PP65.

Yes it is an early 65 ,but the steering nozzle has been replaced with another or modified ,and the nozzle actuating rod attachment point is missing. It appears from the picture that the nozzle won't work in that application ,but to be sure post some pictures from other angles ,sometimes one view is deceptive.

the jet drive was recently fitted on a boat and in use till the engine oil cooler pipe split and the engine seized up.

the steering nozzle turns ok. i was going to make up a steering mechanism for it unless i can get the right part for the steering.

the bloke i got it off took the jet drive off the boat then ended up scrapping the boat with the steering still in it. idiot.

i will get some more pics tomorrow ok.

cheers for that dave. do you know where i can get the steering system for it from.

anthony goodson

01-09-2011, 04:24 PM

Garrybull the telescopic actuating rods for your reverse bucket and steering nozzle are an integral part of a teleflex cable . My concern is that I cannot see a point on the port side of your nozzle where this rod would be attached.Various modifications have been made to these nozzles ,and if you post more pictures then all may be revealed ,it may be that you have another attachment point or lever originating from the swivel point of the nozzle but I cant see it in the photo.

garrybull

01-09-2011, 04:36 PM

anthony there is a fitting on the nozzle for the steering cable to attach to. i'll have more pics of it tomorrow or tuesday ok

windydave13

01-10-2011, 02:54 PM

Garybull,

I've been out and taken a few pics of the steering setup on my Dateline. Whilst it's not a PP65 unit it is very similar.

As anthony said the cable itself is a standard Morse/Teleflex unit, but you need the bit of kit you'll see in the pics to link it all up.
If someone can tell me what it's actually called i'll be very happy as mine needs to be replaced.
It basically consists of a plastic balled housed in 2 ally cups which alow it to move slightly. The cable screws in at one end and then bolts to the nozzle.

Apologies for not showing the nozzle and stator in mine, but they're on the bench awaiting paint.

Hope it helps

Regards

Dave

If you can't see the pics let me know

garrybull

01-10-2011, 03:32 PM

thanks for the pics dave. do you have any problem with water getting in the steering cable?

garrybull

01-10-2011, 03:37 PM

dave any chance you can take a pic of the grate underneath your boat so i can get an idea of how big i need to make mine. cheers

windydave13

01-10-2011, 03:44 PM

Garry,
I'll try and get some pics tomorrow for you.
As for the water, i did, but i made a a seal out of an old inner tube that i packed full of grease then cable tied both ends. The end on the cable was just tight enough that the cable could move in and out. Seemed to work quite well. Saying that i still have a leak somewhere but i'm hoping new seals on the drive shaft should sort that one.

Dave

garrybull

01-10-2011, 03:52 PM

cheers dave. appreciate it if you can get pics of the grate.

windydave13

01-10-2011, 04:09 PM

Here you go fella. Good job the old girl is under cover as it's a little moist out there tonight.
The pics aren't the best but it's not easy crawling underneath in the dark with the camera in one hand and a tape in the other.

If you need better quality i'll take some at the weekend when the light is better

It might be worth speaking with Brent Voce (T +44 2392 53 9739 ) at NAIAD DYNAMICS UK LIMITED. He was very helpful when i was after details when i thought mine was a PP65. He might be able to give you the exact dimensions of the grate.

Well done Dave ,a picture paints a thousand words and that manual you posted was a real find ,it,s 25yrs since I saw one of those. Garry, I had time to enlarge and examine your photo today and I can now see the arm that the steering cable attaches to, should have gone to Specsavers , that nozzle will be fine. Dave has posted pictures of the parts that you need ,but what the ball and sockets are called I don't know.This was the original version of the 65 which became the "economy" when it was superseded by an updated version ,very similar to the 90A. This had an internal nozzle turning within a bowl ,which was actuated by a torsional bar connected to a transverse lever in the boat, rather than telescopic rods ,as was the bucket. Thus the cables were inside the boat and less prone to the corrosion and leakage which I regret to say yours can suffer from .

garrybull

01-10-2011, 04:29 PM

anthony i'll have some more pics tomorrow for you ok.

anthony goodson

01-10-2011, 04:38 PM

Dave you seem pretty well up on this so I expect you know ,that the front bearing is a standard off the shelf bearing ,the rear bearing is just a DU bush and all the seals are standard automotive ones but with stainless steel springs. Garry might appreciate this information .

garrybull

01-10-2011, 05:42 PM

yeah been told that already anthony. got a local bearing place where i live so once i've stripped it down i'll be paying them a visit for new bearings and seals.

cheers for all the help and info guys. being my first jet drive i wouldn't know where to start with it.

windydave13

01-10-2011, 05:57 PM

Anthony,

Cheers for that, but it seems mine is a "West End" unit rather than a PP65. To be honest they seem pretty similar but i've got a number for Sam at West End Marine so going to check with him to see that they are standard bearings before i start trying to install the new ones. I've only just got the bearing housing and drive shaft out the unit, so now i can start stripping it down.

Out of interest is there a technique for removing the seals that go between the transom/jet unit?? I've had a little look this evening but i don't want to just rip them out then have issues at a later date. I presume i don't have to seperate the unit from the boat to remove them???

anthony goodson

01-11-2011, 05:37 AM

Dave
Do you mean the 3 shaft seals ?

windydave13

01-11-2011, 05:50 AM

I can only assume so.

It's not the seals in the aly bearing housing but the ones pressed into the casting where the jet unit meets the hull. I'll try and take a picture later

anthony goodson

01-11-2011, 06:28 AM

Sounds like the shaft seals ,there are three of these just pressed in nothing special about them except stainless springs ,just take the numbers round the face to match .When you have hooked the seals out ,you will see a small hole in the roof of the tube they sit in ,this is to allow grease to be injected between the seals through a tapping and nipple on the front face of the jet The two seals nearest the water sit together with their springs facing the water. Then you leave a gap so that the grease hole is not covered ,as you insert the last seal ,facing the same way as the others.I used to cut a thin section of slightly oversize ss tube and split it to leave a gap ,insert it and then check with a bent piece of wire that the gap matched the hole and leave it in there. Not by the book ,but I felt it helped to keep the seals square.

windydave13

01-11-2011, 06:52 AM

Anthony,

Cheers for the info. It's not the easiest seeing whats in there at the moment esoecially with the dark nigths and the fact i haven't got enough head room to lift the engine clear of the boat. Hopefully i'll sort that this weekend with a bit of fetling!!

anthony goodson

01-11-2011, 07:20 AM

Dave don't be afraid to remove the jet unit from the hull , unless it has been sealed with sikaflex. These units go back and line up very easily and are not prone to leakage at this flange ,you don't need to do this to replace these seals ,but you might bear it in mind in the future.

anthony goodson

01-11-2011, 01:47 PM

Garry ,the penny has just dropped ,you didn't get the intake box with your jet ,I was idly wondering why you needed the grill dimensions and then I realised. On this jet the forward part of the jet comes as a fibreglass moulding ,which you bond into the hull . The design and dimensions of this are critical to the performance of the jet you would be very lucky to get it right just with rough measurements ,you really need a moulding or a mould off another intake.

thought i might have to make something up. i'll email VT and see if i can get any info. i was going to make up a tunnel in the bottom of my boat about 2-3ft long and at the front of it i was going to open it up a bit wider so it will start at about 12" wide the narrow down to the width of the intake on the jet.
i'll see if i can do a drawing on my computer so you get an idea of what i mean.

also got some pics today for you. will put them up shortly ok

01-11-2011, 02:14 PM

Thanks Garry that's just as the nozzle should look ,I could not see that on your original picture. Regarding the intake think it would be advisable to research and maintain the original intake dimensions and profile ,the effort made now will pay you back in the longterm , perhaps Niaid will provide a drawing.

garrybull

01-11-2011, 02:20 PM

if someone can come up with a drawing or pic of what it looks like that would be great.

its not a problem for me to cut the boat out to fit the intake. will only take me a few hrs and it will all be glassed up and finished once i know what size i've got to make it.

windydave13

01-11-2011, 02:49 PM

I'm hoping to have the engine out of mine this weekend so i'll take some pics from the inside of the intake and when it's brighter take some more pics of the under-side
Dave

garrybull

01-11-2011, 02:52 PM

cool cheers dave. appreciate that

anthony goodson

01-11-2011, 03:26 PM

Garry bear in mind this box also sets the shaft angle of the jet ,from memory about 5 degrees down but check this with Niaid. This is often less than transom angle so you have to let the top in.

garrybull

01-11-2011, 03:36 PM

ok anthony will remember that when i come to fit it in a few weeks time.

could it fit a spacer to the back of the boat to get the right angle. i can easily make a fibreglass spacer at the angle it need to be.

anthony goodson

01-11-2011, 03:45 PM

Well if you do that make sure to extend it as wide as the base of the jet ,or it will try to suck air under high suction conditions.

garrybull

01-11-2011, 03:49 PM

i will make it bigger by about 2" all round and glass it to the back of the boat so it becomes part of the boat

garrybull

01-11-2011, 03:51 PM

anthony maybe you could pop up one day when i get round to fitting it if your up for it. would be good to have someone there who has got experience with the jet drives.

im near portsmouth so not a million miles away.

anthony goodson

01-11-2011, 03:55 PM

If i'm in the UK at the right time ,I spend much of my time in Spain.

garrybull

01-11-2011, 04:01 PM

ok mate. i won't be fitting it for a few weeks yet. will be picking my new boat up in 2 weeks time then i can start working on it.

i won't to get the jet drive fully overhauled before i fit it so will be a few weeks before its ready to be fitted

anthony goodson

01-11-2011, 04:11 PM

what is the new boat ?

garrybull

01-11-2011, 04:15 PM

its a 23ft wilson flyer. i have bought the hull with ribs fitted , gunnels fitted and bonded on and the forward wheelhouse.

first job will be to fit the deck and transom board , then fit bulkhead in wheelhouse then make the engine box. once thats done then i can think about fitting jet drive and engine

anthony goodson

01-11-2011, 04:35 PM

I have to be honest with you here Garry. that jet is far too small for a Wilson 23. We have two Wilson's in the family at the moment a 20 and a 20 reduced in length by Wilson to a 17 ,both with jets so I am not guessing I know. You will need a 9inch jet for that boat at the very least built light .A 10 or 11 inch would be optimum. Sorry to be the bearer of bad news.

garrybull

01-11-2011, 04:39 PM

hmmm. im not after a really fast boat. if i can cruise at 20 knots id be happy and if it did 25 knots flat out id be chuffed to bits.

what size jets you got in yours? got any pics?

anthony goodson

01-11-2011, 05:04 PM

Hard to accept I know ,but trust me just don't do it. A lot of time and money and you will end up with a boat that will never be right. The history of jets in this country is littered with failed projects that were missmatched from the start, at least you have the opportunity not to make that mistake. Both our boats have 9 inch entry 10 inch exit mixed flow impellers.

garrybull

01-11-2011, 05:18 PM

have you got any pics of your boats?

anthony goodson

01-12-2011, 05:54 AM

Yes I do have pictures somewhere.I will look. Garry ,forget the jet ,any jet ,it will just be too ineficient in the speed range you are aiming for. You need a propeller either on an outboard or a leg. Here is your next dilemma, up until recently I would have pointed you towards a Transit diesel engine on a leg,yes I know it's an old clunker ,but readily available secondhand ,totally reliable, and upgradeable to 140 hp with turbo and intercooler just right for your boat. But whilst we weren't paying attention politicians ,mainly bliar, moved the goalposts. From last year it has become illegal to use lower taxed red diesel as a propulsion fuel in a leisure craft in the UK. Diesel for leisure marine use is now£6 per gallon and rising, the 100 dollars a barrel mark is just around the corner so that doesn't bode well .Petrol too is expensive but of course the installation costs are lower. Now this petrol/diesel/outboard thing has been chewed over many times on here, safety,reliability economy versus lower installation costs and weight ,explosion risk, and electrical vulnerability and so on ,but perhaps you should start a new thread to take into account the new circumstances ,and projections into the future. I understand that new generation outboards are more economical but I don't know by how much. The auto industry has certainly reacted and my new diesel car has amazing economy ,but the marine leisure industry appear to be stuck with paint it green and treble the price, You have made a good value choice buying a Wilson 23 ,so ask the question on here about your next step. Good luck

they look nice mate. bet they go well.

been thinking that im going to put the jet on hold while i build my boat up and when its time for engine to go i'll then decide what route im going to take.

deffo got to be an inboard diesel though.

thanks for all your help and info on the jet drive. may still need to ask you more info in the future.

anthony goodson

01-13-2011, 03:52 AM

Ok Garry good luck

windydave13

01-13-2011, 04:08 AM

Anthony,

Cheers for the info on those seals. I've managed to get them all out and strip down the bearing housing now. I've found a local seal supplier so they're sorted but do you know if the bearing needs to be stainless or not??

Regards

Dave

anthony goodson

01-13-2011, 05:06 AM

No it's just a standard bearing ,should be a double row deep groove ball on that .It's protected from moisture by the seals . There should be a drilling in the bottom of the bearing housing to allow any water that finds it's way past the seals out ,before it damages the bearing Check that this is clear,they tend to block up with grease. This tell tale gives you the first indication that your seals are leaking ,keep an eye on it These jets in the beginning were very small volume and off the shelf parts were used where possible.
nb I am assuming same as 65.

windydave13

01-13-2011, 05:34 AM

Anthony,

Cheers for the reply. When i first got the boat i thought it was a PP65 but the fact "West End" was cast into the reverse bucket gace things away that it wasn't. It turns out it was made by West End Marine in Yorkshire but basically to the same spec as the PP65. I've been using the PP65 manual to strip it and the only differences i've come across so far have been additional seals. There were 4 in the transom area and then another 3 in the bearing housing, which puts 6 seals between the bearing and the water. The bearing i've removed doesn't have a hole drilled in it but that could be just for this unit. Overall everything is looking in quite good condition, bar the old seals and bearing so i'm hoping with some new parts and the impellor adjusted correctly i can get rid of the cavitation that was occuring at high rpm and maybe even get it to the point where it can pull me ski-ing

anthony goodson

01-13-2011, 07:43 AM

If there isn't a hole there I would consider creating one .Perhaps mill a slot at the bottom where the housing bolts onto the body, this joint doesn't need to be air or watertight ,it may save a bearing.

Hi I’m new on this forum and saw your discussions regarding PP jet. I just bought an PP jet 65 and was looking for some knowledge on this. Most of it is pretty straight on but the intake puzzles me. I saw Garybull drawing and pics on intake and bottom of hull. But it would be great if someone have some measurements or pics on whole bottom shape. I will install my engine and Jet on a 16feet open boat powered by 150 BHP Volvo aq140. At moment I’ gathering data and info until winter lets it grip here in Sweden before I can start work. Will install engine and jet on test platform before install in the boat.

anthony goodson

02-18-2011, 11:00 AM

Welcome flipp640 ,The PP65 aluminium jet casing forms only the rear part of the intake ,the forward part is a pre moulded GRP box which is bonded into the hull ,this aligns the jet in the boat ,in that it sets the correct transom angle and can be laminated in to provide a smooth transition over various deadrise angles. The shape of this is important and measurement alone is unlikely to be enough for you to create one.
Perhaps you could take a mould from whatever hull this jet was removed from.

flipp640

02-18-2011, 12:01 PM

Thanks for your reply. Sorry to say Sweden is still very conservativ against water jet so jet propulsion is rare :(. I imported mine from UK . since my last atmpt with an 1100cc jet from a Kawaskai PWC was unsuccesful I wanted a bigger jet and saw PP had the intak to the jet on outside and I though this would be easier. Ok so it will be learning by doing case :).

anthony goodson

02-18-2011, 02:22 PM

Flipp 150hp in a 16ft open boat,means a fairly high speed ,this is where intake design becomes important. Brent Voce at Naiad Dynamics can be very helpful,maybe he has a drawing, his detais are on this thread, alternatively Windydave has contact with a company that produced a similar jet ,maybe they can help I haven't worked on a 65 for some years now but I wil look through my old papers and see what I can find ,I think a line drawing of the profile from a spec sheet is the best that can be hoped for there.

baeckmo

02-18-2011, 02:23 PM

Flipp, I have been doing quite a few things both with PP/Vosper jets and others over the years. Understand you are in Sweden somewhere, give me a mail with your phone nr and I'll call you.

Btw, you are pretty off center regarding waterjet "culture" in S, but we can adress that over the phone.

Well i been reading every ones helpfal advise and now im worred lol i have a fast worker 19 with a pp 65 jet fitted befor i bought it it had a nissan with a 2.7 diesal in it as some one spent hundreds of pounds fitting this jet with strengthan stern all ss guard around the jet new deck raised gunwalls by 6 inches I put a front wheel house on and up raited to a Tarreno Nissan 2.7 turbo that will run at 6000 rpm plus i now have a seed of dought if this will work after 4 yrs work i will find out how it will work the end of march when it will hit the water for the first time, I will let you guys no what happen's but i think some of you will no we will see .

anthony goodson

03-05-2011, 04:16 PM

kcmd, there is plenty of help here if you need it. Are you sure it's a 65 ?

kcmd

03-05-2011, 09:09 PM

Yes Anthony im 99.9 sure its a pp65 looking at the pics on here and by what other's have said only the bottom steering fine has been altered made a little larger I would put some pics on here but still have to work that out, You see it was not untill i read about jet drives on here did i think it might not work . When some one have spent thousand or two, converting it to jet from outbourd with houndred.s of pounds on stainles steel guard for the jet and ss exsuste befor i bought the boat i assummed it would work.

anthony goodson

03-06-2011, 03:55 AM

I think you realise what the problem might be ,too much boat ,too little jet , but stay in touch and let's see how you get on. To post pictures just scroll down to manage attachments on the go advanced reply page ,this will upload the pictures of your choice from your computer.

Hello guys.

We are working on a hobby project building a audi tdi 2,5 180 hp in front of a pp 65 jetdrive.
Our first plans were to leave the gearbox on the engine, because it will give go an over drive. So the boat will run faster, but the problem we are facing is we need an other impellor right rotating, the standard one is left rotating. I think that is imposeable to find or to make. The impeller we now have i a 3blade, for the best result we forget the gearbox and need four blade. The stator of our jetdrive has 7 holes, so that sould not be the problem. So if anyone now how to get a four blade impeller, we should be pleased. I hope my english is readable.:)

Welcome Jetty ,not only will you be unable to source a "right rotating " impeller but if you did you would quickly realise that the volutes in the stator unit were now orientated the wrong way ,so that's a definite no. You are quite correct ,in that a seven blade stator runs best with a four bladed impeller and 180hp is right at the top end for a 65 ,probably off the scale ,the man to speak to is Brent Voce at Naiad Dynamics 00442392539739. You can e-mail the Portsmouth depot services@naiad.com or there is an office in the Netherlands sales@naiad.com. 0031436049200 but I don't know if this office deals with waterjets.

Superficially similar ,but different pump characteristics. Axial vs Mixed Flow.

Good morning Mohawk. Wikipedia has a very accurate and concise explanation of the different characteristics of axial ,mixed flow ,and radial pumps,all you need to know really. Just type" pumps " into Wiki. It's some years since I dealt with a 65 ,and could only guess at the dimensions of the wear ring,apart from the 6.5 inch entry, however Windy Dave who posts on here has one in pieces at the moment ,perhaps he will measure it for you.
The 65 was ahead of it's time when introduced in the 1970's. The tapered wear ring , sliding polyacetal collet ,mixed flow impeller ,and dry run DU bush stator bearing were all unique at the time. Richard Parker was a very clever gentleman.

I can see there has been some Swedish activity in this thread. Does anyone know if it is possible to find pp jet parts in Sweden. I have a boat fitted with a pp 90 jet. However with the boat came drawings for a pp 90 and a pp 90g jet unit. How can I tell wich one is on my boat, and what is the difference.
