Guys....................................................
Has anyone here converted a car motor to run in a power boat. I have bought the plans and I am going to build a Riva type boat, starting this summer. First I need an engine to fit in the hull so I can take measurements etc and build the hull to suit.
 I have thought of using the Omega 2.5 TD motor as it has plenty of torque right through the rev range. I will need to cool the manifold and the exhaust, as it is a wooden construction, which I haven't worked out how to do yet!
Is this a feasable option using this motor or does someone have an alternative idea. :-/ :-/

Have done this using a perkins engine, MILNER do a "marinization" kit which is very cheap. You will need afilter kit too for water cooling to take away the possibility of fish, debris, etc going into the engine. Easy to do, and really a good option if you want torque, but not really balls-out speed. If you want speed, go for a "ROCHESTER" conversion on a 2.2 miggy engine with fuel injection. Goes well, and quite cheap too!!

Mike, point me in the direction of the rochester conversion.The boat is designed to hit 55mph. Web link or what ever would be appreciated

Go for a V6

Go for a V6

Trouble is it might have to be re cammed to get the torque right through the rev range. :-/ :-/

Just tried to get a web link or similar, can't find a website to link to. My buddy next door has done two petrol conversions, but says diesel is the best cos you can get marine diesel (red) much cheaper, and available on the waterways easier than petrol. use a Perkins 4182 or 3.0 turbodiesel and you will get petrol performance from a diesel engine. find one from a Vaux Monterey, or an Isuzu trooper Duty and it will be cheap as chips. Milner conversion includes all water manifolds and filters, and will cost approx £500 with all mounts and rubbers too.
IMHO the best bet, as he says petrol conversions are fickle and suffer from atomization problems that turbodiesels don't  and apparently mileage doesn't matter much in a diesel, but ideally you need an engine with less than 70k if you go petrol due to revs, and TD,s are governed so its ok.

Hope this helps you, he's a real font of info.

diesel engine good choice imo but I would recommend one this

as you may need soon

Thanks Mike
I think the TD is the way to go as I don't want to get into changing cams on a petrol engine to get max torque throgh the rev range. I would love to put in the MV6 engine in though just for the sound

Talk to Milner, they do a SMASHING Volkswagen 2.5 TD conversion, and a brilliant V6 diesel one too..........

just remember to direct exhaust to the stern end or you will get soot all over the boat, and induction should be K+N and have a drain off facility. Fuel tanks should be plastic, and pressure pumps should be Facit ones.

If I can help, ask.
