just a thought here and maybe I'm reachin out a bit,but, in addition to all other possible factors that are making the boat porpoise up and down, not reaching wot rpm, what appears to be low top end [43-44mph w/ a225???] could the t-top be pitched in the wrong direction???? Meaning is it catchin to much air and acting sorta like a parachute??? T-top, lotsa fuel[the tank is kinda aft,isn't it?] a HEAVY motor.....all that is certainly not any help if your looking to keep the bow down. Bottom line is that 225 should get you a least 50-55mph and about 900 more rpms. Airslot brings up a good point as well, I think it may be hard to tell if its not firing on all six, not being to familiar w/ the motor,it may be possible to overlook ???
