[Rick R]

does anyone make an adaptor from chevy 229 engine to buick3.8 for omc 800 sterndrive

Ayuh,..... Welcome Aboard,..... I know OMC used both of them motors, but donno what parts you'd need to mix, 'n match to make it work,.....

No adapter per say, just the right mix of hard to find parts,.....

You would be better off using a 4.3 chevy, and having one of the Ford OMC coupler buttons remachined to use with the 4.3, unless you can fine the ultra rare 1985 4.3.

Marine exhaust for the buick are hard to find. OMC flywheel housings for the buick 3.8 are even harder to find. Remember, OMC went out of business over 2 decades ago

ok I think I will just remove the original engine 1982 3.8 chevy v6 and rebuild it any idea how many bell housing bolt are there and do I need to drop the starter to remove the engine I have a engine hoist that will pull the engine out of the boat I have a seloc manuel it doesnt show the bell housing bolt pattern and engine removal section is not very descriptive

 

[Scott Danforth]

You pull the dribe, disconnect the transom boot, then take the lag bolts out and remove the motor and bellhousing as a unit
