But many people don’t take their boat out nearly as often as they drive their car, so it makes sense that marine motors are not built to be used the same way as car engines. This is why you can’t simply use a car engine in place of a boat engine. Marine Motors Come in a Few Varieties

A 350 with an RV camshaft will be closer to the marine engine than the average car is. I don't know how heavy your boat is but if the marine engine had to work to get on plane you might not like the performance of the automotive engine. If the boat had all kinds of power to spare, the automotive engine might make it plane just fine.

Yes, you can use car motors. We do it all the time. But be aware, a boat is a different animal and you can easily overheat and destroy your car spec motor. Consider this: a boat prop is always putting a load on the motor. Unlike a car, where it will reduce resistance once it is rolling. So a comparison might be like this: holding the tires still while trying to turn them over with the motor. Lots of resistance. That is what a boat is like.

They tend to run these engines a lot colder, so the cylinder clearances have to compensate for that, and so do all the other clearances. You look at a normal car engine and it’s probably running a water temperature of 220. There’s no way you can do that in a boat.

Most fuel injected auto engines have a pump in the fuel tank that pressurizes the fuel lines. You don't want pressurized lines running through your boat, so you can't have the pump in the tank. On boats the fuel pump is near (within 12 inches) or on the engine and fuel is sucked to the engine rather than pushed.

Re: Can you use a Car Carburetor on a boat I had the Holley 4bbl 750cfm laying around the house thought i would rebuild it and put it on the boat do you think it would be safe if i used some pipe on the overflow tubes so the overflow goes back in the carb.

Check out this basic conversion step by step procedure that may help you in converting auto engine to marine use. Step by Step Procedure. Detach the exhaust headers from the vehicle engine using appropriate tool. Remove and disassemble the carburetor. After that you can now remove the pulley as well as the water pump from the engine.

If the float sticks in the bowl and fuel flows out the vent on a car it goes out of the carburetor. On a marine carburetor it goes down the throat. Marine carburetors are not allowed to spill any fuel into the boat. Plus that, marine carburetors have different jets and setup because of the different duty cycle.

Depends, the short answer is most likely. The long answer depends on the grain size and which part of the engine the sand entered, if it was in the oil sump there's be a fair amount of grief (im not so sure how you’d get it all out and be sure) but if it somehow entered the combustion chamber it could be ok provided you cleaned them out.

BS. Yes it will work , boat engines are build a little looser then car motors on the specs so they can actually work at 5200 + RPM over a piriod of time since boats do not use a tranny. other then that its the same..if its a HP boat engine, u will have better exhaust valves and stuff too.
