Trojan Boat Forum

I was wondering do I have to add more oil or the regular amount of oil that a car Ford 351 takes? I want to change the oil in my boat before I take her out this weekend. Also this may sound dumb, but Ill ask anyway, What is the deference between regular Ford 351 and a marina Ford 351. They say dumb question is one that is not asked.

well on my bbc's all the extra stuff to cool it, and the cams are different I'm sure one of the mech's like Paul will be along to give all kinds of info.

And they have a marine alternator. I think that is important for some reason. Oh yeah, I remember the guys said you might BLOW YOURSELF UP if you used a Car Alternator. If not for yourself, man, think of your Dog. Or Wowzer's penguin.

Head gaskits , many times forged pistons insted of cast pistons cam can be diffrent and of course alt /starter and carb


they use diffrent pans so it will take 5-7 qts of oil .BTW I have used 15w-40 oil in all my boats for years gas and diesel

rodman, To makes things more complicated, ford built 2 351 CID engines.
The Cleveland, a high performance block ( remember the BOSS Mustang ) and the Windsor, more of a work horse often used in trucks and marine. As stated, the pan is differant than in a vehicle as the engine sits on a wider angle/degree when installed in your boat, therefore, a higher oil capacity is necessary. jimbo36

The Cleveland also was used in trucks and was made in low HP ratings also .Very rare in marine use ( a few small builders used them ) . The 351 winsor is a great boat engine IMO.
