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 :y :y

Go for a V6 :y :y

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

Thanks Mike :y
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 :y
-
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.

Surely putting a straight 6 in that would be like putting a straight 6 in an AC Cobra? Just not done. Needs a V8 IMHO. :y

There is a finance thing too, for me looking at a tourquie deisel. I would love a V8 but the grunt is not right through the full rev range. It would have to have a cam change or drastically chipped. Down to cost :'(

Doesn't have to be a petrol V8. ;)

What out of?
I have noticed though, that its cheaper to buy the whole car than buy the engine on its own.

Hmm. You will start to struggle at this point. ;)

Yes, with the advantage that you might well get to drive the car and decide if the engine's a "keeper" or not.
I guess someone who's stripped a car is looking to make money from the parts - compared to someone who just wants to get shot. :-/

Problem with a V8 diesel is the weight or any diesel to that matter. I don't want to be belting round in this boat but a nice turn of speed when wanted is all I require. The boat is rated at 55mph but 40mph would be fine. I also want to use it on inland waters so obviously not to noisy when 'putt putting' around. :y

What about using a Transit 2.5Di diesel?
I happen to know of a few just taken out of vans.

Not sure really, need as gutsy a motor as I can get but not to heavy :y

Kev....trannie motor is heavy, and doesn't lend itself well to marinizing, Milner specifically advise against it.
Stick to TD units that rev freely, such as Perkins, VW and peugeot /citroen 2.2/2.5 HDi units, and if you can get one, especially good is the Toyota TD units from the avensys.

The Omega 2.5TD is not exactly light. I reckon you could do much better on the power:weight stakes.

Yes but as Byron says, he knows of a couple of transit engines. They are not the lightest and definatley not the most powerful. Going on your theme maybe a Sprinter or Movano ( both are quick vans) open to suggestions here!

Bit frustrating that I can't start my project until I sort this out. But I do know there are some very astute guys on here that will come up with something, like yourself! :y

a omega fuel tank is plastic/rubber as well
might be a bit big ;D

Not my priority at the moment r1 but I will keep it in mind. :y
Know anything about the most powerful, lightest and cheapest diesel you can find? :y :y
