John-I commented on your post yesterday about this. A 24p fury would probably be a good one. I had decent numbers from a 24p fury with my 4 stroke. 60mph solo. 55mph with 2 guys and empty livewell. The 25p may work for lightly loaded conditions, but if its you and another guy with tourney load, probably looking at a 23p tempest or 24p fury. motor height is kind of by testing… a tempest prop will probably have to sit a little higher than a fury prop. Again Im working with a 4 stroke and have a fortrex 24v TM system and am a heavier guy, so I have to run a little bit less pitch and a little lower on the plate for my setup.Jared
