re: Questions on my Xpress H22 setup

ok...where to start.. throw away that powertec. the xpress likes the trophy, pro series and tempest props the best. For a trophy you will need a cavitation ring as its a small barrel prop but runs very well on the xpress.

OFX3R21PCL200 : OFX is the style powertec. 3 is the blade and 21 is the pitch

you want your prop to pad to be 4"-3.25" with those props. - get your motor set at 4" below pad. mark this on the JP - do same for 3.25". Stay between these two marks when running. drop JP to 4" and get on plane bump up and slowly bump trim until you lose speed or lift. bump down one and that is your wide open motor height and trim level. at this time you should be at max speed, lift and 5800-6000 rpms.

you want 6000 rpms with your average load, not a light load that you never realistically use. fill the tank, put 2-3 guys in there with gear and see how it runs. All props of the same pitch will give different rpms due to diameter, blade design and blade stiffness differences. you should be turning a 19 pitch. maybe 21 depending on the prop but thats a lot of boat for the 150 so a 19 seems best

props lift lots of rake run good on the xpress to give it lots of bow lift to get on pad. the 4 blades lift the stern in addition to the bow so they run a little "flat" when compared to the 4 blade. I ran pro series (3 blade) and trophy (4 blade) on my boat.

if you want more speed, get a bigger plate (10-12" of set back) xpress likes as much set back as you can give it.

Water pressure - say about 12psi. you run at the motor heights i said you wont have a psi issue.
