How'd you get on with the dis-memberment of your unit now you have the manuals???

http://www.hamiltonjet.co.nz/obsolete_waterjet_manuals From here it's pretty simple to get to either the old workshop manuals or owners manuals. As previously mentioned, the Kodiak jets are modeled on (pretty much directly copied) the 770 series Hamilton waterpump. When needing replacement...

We've powered ours with everything from 3.8l V6 Buick engines, Chev Vortec engines, and Chev LS2 and LS364's, coupled to either Hamilton HJ212's, Scott Jet SDM 200 and 600's, and American Turbine SD309's.

early jets had the engine well forward with a long driveshaft. When Hamilton jet went to the axial flow multi-stage jets they'd keep the 'stages' inside the boat and maintain the transom seal over the tail peice. What sort of shallow water dwl are you after? We build a 15'5" boat with an...

Wow, that's a complicated setup if you run injected headers, why not just run a priority cooler with a built in mixer, that way you get a bypass for rock steady idle and wot temps with no increased block pressure, but the mixer 'mixes' the hot water comming out of the thermostat with the cold...

Moving the unit back is a definate speed advantage. Using the boxer 4 or 6 from Subaru will mean you could place the engine over the pump and still maintain some level of COG. One thing to be aware, the jet-ski type jet pump requires to revved reasonably high when compared to the Subaru, if you...

CDK, if that is a pic of the transom of your boat I can see what the problem would be. How many different jet pump manufacturers had you looked at before 'jumping in' to the twin berkely install? How much jet pump tuning did you do? What RPM are you pulling. Do you install an outboard and put a...

also found these guys that do something similar, worth checking... www.seabrookemarine.com

Seem to recall seeing an article in a local magazine that they were being manufactured in Austrailia. Expensive, but very nice. Not sure about the plans though

The question is incomplete... How long are the boats, this will have an effect as to wheather of not they can span shorter wavelengths. What is the deadrise? As pointed out about speed compounding the load / shock issues, the greater the deadrise, the lesser the 'impact' I assume at the...

If you have to pump the fuel a long way, then you'll need an high flow pump to suck from the tanks feeding a high pressure pump. The high pressure pump feeds the fuel rail and injectors (around 40 - 60 psi) I wouldn't place the high pressure pump at the bow, as you don't really want a long...

Does anyone have any leads on when Mercury will start bolting their 4-stroke power heads onto the Sport Jet package? We get alot of enquiries regarding this, but as yet have no reliable information.

ozjet... Had you thought of using a universal joint, easy to machine an adaptor block to the flywheel and bolt right on. Try to avoid the centa-flex rubber doughnut type, as the speeds that the LS1 revs makes the mass of the rubber too large and it tends to grow out of shape, or worse fall...

How big of a boat are you after. The merc sj175 does offer a reasonable amount of thrust, but the downside is that in their infinate wisdom, Mercury put the exhaust from the engine in the cavity between the hull and jet unit. While this doesn't effect performance, if you have an alloy boat it...

send some pics so we can ID the pump, then we'll have a better idea of what you are after

can you post some pics?

Oh dear, I've just seen that Mathewf has beaten me to this board!

We've run alot of the LS1 and are now starting to use the LS2 for our jet applications. We use the Delphi computer with a modified program for the marine use. Running without the O2 sensor isn't really to much of an issue. The O2 in a car only makes very small adjustments for fuel (narrow...

have a few pics on our site. www.speedboats.co.nz We are currently involved with some 11 passenger boats in NC, and we expect there to be updates as progress allows. Hope to add pictures of the build and of the finnished boats underway.
