I am considering an old '68 Starcraft equipped witha Mercruiser 120 (152 Chevy) as a summer/fall toy project. Can anyone give me any info on this engine/drive? Are they fairly reliable and easy to work on for a shadetree mechanic?

Jason,<br /><br />They don't get much simpler than that. The drive was reliable as was the engine-albeit a little underpowered.

FWIW the boat is an 18' Aluminum V.

Jason,<br /><br />I'm familiar with the boat. It was my experience that an 85 hp. outboard would run with and sometimes outrun the 120's.<br /><br />They ran smooth and quiet, that's why they were so popular.

Re: Old Mercruiser

Thanks Djohns. I am almost finished reworking a '76 16' t-hull with an 85 Johnson and thought this one might be fun. I would really like to use it as a cruiser on my often choppy local lake while getting better MPG than the Johnson and more umph to pull a skier up.

Jason,<br /><br />It will make a nice cruiser for choppy water, quiet too with better econmy. Don't expect much in the ski department however.
