Could you give me more info about my boat

@fallguy

I did not understand this part of your post very well "For a motor with such low rpm limits, I'd say you'll have plenty of torque available, but still a guess.". I was not concerned that the boat will not have enough torque, rather if not too much torque is transmitted from the engine to the drive since drive can take maximum up to 350 lb-ft. For the outdrive would actually be better to have higher RPMs at same power level so that torque to the outdrive is lower. Anyway, I did not understand that sentence very well.

 

Disregard. Like I said I read fast. Somewhere I thought you had concerns about enough engine torque. Just a misread.

 

Move your post to propulsion friend. You'll get lots smarter people than me to answer.

 

Dear Nidza,
I have an exact same boat as yours. Can you tell me where you are based and also what type of carier you have your boat transported and what car you use to tow her?
Thank you for answer. Luk

 

Dear Luk,

I only have the custom built trailer for moving the boat in and out of water (with four forklift wheels), not for the transportation. To trailer in and out of water big jeep or truck can be used. I did transport it only twice, before and after renovating, and I payed for the service (once it was a big jeep and once it was a truck and the trips were very short). The big jeep did it slowly and it seemed safe.

Can you attach some photos, I would love to see the boat.

Regards

 

Thank you for your answer. I do not know well how to post a picture. Did it arrived well? The boat is laying long time on shore. The original engines where replaced by two marine ford engines. I am not sure how much horse power, but it should be a lot.

Thank you for the photo.

You will have a lot of work,but it is very nice boat. I saw it on subito yesterday. If you need any help or if I can help you in any way or with advice or if you need the brochures and diagrams feel free to contact me.

About the transport, mind that the boat is heavy,a lot of material is in the hull. Long ago,it was possible to transport them with train so check if still possible and compare the prices. The boat is almost 3m wide so you will have additional costs if transported by road.

About a lot of power,depends how you will use the boat. From my perspective, I think that shafts would be so great instead of outdrive(s) and I would use it only in displacement and a bit above that speed which is possible with this hull and with realtively small engine,maybe up to 80hp in case of single engine. In case of single shaft it would have to use V gearbox (due to hull structure) and in case of smaller twins it could be either V gearboxes with engines at stern or direct shafts with engines in place of fuel tanks. Of course in the last case,some modifications would have to be done to passive ventilation system and engines would have to be sealed from cabin bilge. If speed is what you want,and you have no problem with outdrives maintenance then you already have a propper combination. Mind that this boat reaches 11km/h with only 30-35hp and that is in my case where the boat is extremely stern heavy due to very heavy diesel engine. With about 45-60hp it will reach 12-16km/h with bigger wave behind the boat, after that it only makes sens to have a lot of power to reach planing and increase speed. You have also an example of other boat with modern diesel for comparison. Slime on the hull can slow your maximum speed almost 10km/h.

It seems that you have a lot of original parts on the boat according to the photo so you will see that a lot of metal elements are actually brass which was chromed. So you will have options of changing them for stainless or chroming originals or even powder coating originals or well,only imagination is your limit. Material is good,it just looses the gloss and shine in time,so if you don't mind you can even leave it that way. Even the windshield frame, bow rail and cleats are made of brass,all inside hinges and window frames...

Wish you luck and send here some update when you can and have time.

 

Thank you for your time to answer. Yes the boat is completely original except for the fact that the original gasoline engines have been replaced by two ford Diesels. I think they have together 130 HP. In the beginning when the boat was still nice, (now after many years standing on land not so much anymore, I have long been looking for somebody who would like to use it for free for a long period in exchange that some days in the year the user would allow to take my children on a trip. Now I am looking for a warf that could both store him inside and do some work on it because for sentimental reasons I can not dispose it. The best option is transport him from Flanders, where he now is, to Holland, where more boatswarfs are. Some 20 years ago I had a friend in Croatia (is this your country) who was willing to take it but his wife did not allowed, (was jealous, fearing he would not look after here anymore. ) I wonder if Croatia would not be a better place to transport and have renovating her ther. What would be your opinion?

 

Just take all the costs into account (transport and restoration price and add around 30-50% on top of that) and then decide. Also think about when and how will you use it and does it payoff to restore/transport it according to that or go some other way.

 

Dear all,
I have the same Bora3 II serie. I have changed the engines with 2 v8 Volvo Penta with 210cv. @ 4200 rpm 25 knod for 55 litre x hours for both the motors. I'm very satisfaction, because before I had 2 engines volvo diesel with 106cv, but with 212cv total I had very problem to reach the glide. I changed it from diesel to gasoline for a matter of weight, because the diesel engines are very weight with equivalent power.
In a future I want to put the original windshield, because the last owner had changed it with a homemade, but for me si terrible.
