IM FROM CONN, and my dads sportsster 215 has a problem or do all the boats do that ,WOT back off on it 1/2 way same speed 55. I put my 13/18 prop in it out of my rxp 7800rpms , want to go to 10/16 is this heard of ,need rpms??

That will not be enough trailing side pitch. That motor's red line (I think) is 8,000. One degree of pitch is about 300 rpm on the boats.

what i cant figure out is at full throttle ,when you back of on it ,it takes 1/2 the throttle back before it slows down ,its pretty scary .do all the boats do this ????????

Mine is the same way and I've tried adding some pitch to see if I could maintain the revs and gain mph but haven't had much luck...revs begin to drop but mph only increases a little bit. It's a real brain tickler but if we could see a big increase in acceleration and mph with that other half of throttle play...yeeeee haaaaa

YUJI, I have a 14/19 solas and running 56.8 on gps at 7800 max,dad just pulled it out and i tweeked it 2.5 mm (decrease) hoping to see 8000 -8100 and some mph, waiting on 2.5 wedge . Got one problem ,step mom will not get back in the boat, i think he's addicted to speed..

The solas sounds about the right pitch but 2.5mm may be a bit much, but I guess you won't know till you get out on the water Let us know how it goes
