Message for Titan25 - Help on Doel Fin Installation

[cloumar]

Sorry Folks,<br /><br />This is my second post on that subject since Saturday - I did get a feedback but I need more reply on this Please.<br /><br />I tried to install a DoelFin Hydrofoil on my 98 Force 75HP and the holes will be very close of the trim tab I am afraid to drill that and make the holes too close might crack trim tab housing - there is may be a way if I push the fins further in but I have no idea how there should be how far in - do they need to be flush with the end of the cavitation plate or they can be fit more inward. Does anyone had experience with DoelFin and Force motor ? Does another type will fit better ?<br /><br />Thanks <br /><br />Smoky

The fin can be in farther that the cavitation plate. How much are you talkin'?

Just leave it off. Trust me.... It will either break the cavitation plate or worse. It puts too much force on something not designed to take it. I ended up with a spun prop shaft.

Hey Rick,<br /><br />about 1 1/2 inch from the rear end of the cavitation plate in order to be far enough of the trim tab.<br /><br />Smoky

That will work. It will still give you the lifting effect your after. Stay as close as possible toward the back of the fin within reason.
