    I am currently running a 25 Yami on my Classic. My Gheenoe has fron and rear deck and a jackplate. Myself and another angler I get roughly 28 mph on stock prop. Is this more or less average? What type of prop would be ideal for my set up? My jackplate is currently set all the way up 3". Also would a Dol-fin help?

    thanks :cool:

    I would like to get a little more top end with not losing to much hull shot.

    Porer tech 12 pitch cupped 4 blade ... I think It's an SRA

    Souped up motor Probably putting out 18 + hp ...

    Go with a 3 blade for more top end. Having a jack plate and raising the motor to the optimal height will get you an additional 2 - 3 MPH.

    Sounds like your not far off.. I have your same setup but i added power trim an it made a world of difference. Not only in speed but ride quality

    A friend has the same motor on a Classic and he gets about the same speed.

    A SE 200 foil was suggested here for the Yammy 25. I have that motor and the foil but don't have it on the boat yet.
