If it's got the "flat back" exhaust cover on it, they were pretty good mtrs.

It is a thirsty beast, like all 2 cycle 6 cylinder motors.

They were solid engines in their day. Yours should have the vented flywheel with a 35 amp high output alternator. Make sure you keep the battery leads tight on the battery posts. You can have major issues with that engine if the leads ever get loose while charging at high rpm's. They put out close to 165 propshaft hp.

Simple to work on. Parts are still everywhere for them. Those heads are available pretty easily too. Older heads a different issue(70's). Those heads are the best OMC put on those crossflows in the '80s. I have a set.
