Has anyone run a 70's era Potter 20'SF with a Yamaha 150hp 4 Stroke? I'm looking at possibly purchasing this setup and was wondering if this engine is too heavy for this boat? If so, I could always sell the engine and repower. Any insight is very appreciated. Thanks in advance.

Put an 150 on my MA before the restore. Had to plug the factory drains. Pushed the boat about 41-43mph. Thats with full curtains, t-top, and bow dodger. Now my floor is 5" above factory floor, so she should selfbail now. I now have 20"freeboard, that is what the SF is factory though. I got well over 4mpg cruising about 25-28mph. Putting a bracket on it so I hope to see 45mph..
