Thanks guys. Some great advice to work with. I wasn’t sure how crucial it would be. Sounds like maybe I should start with no fin and see how it goes. Guess I can always add one later.
I’m building an 8’ Tiny Titan with plans from Glen-L. It will have 9.9 hp outboard. It’s for my grandkids. Not sure where to put fin to allow for good steering in either direction. The directions say left side because most races run counter clockwise.
