Hey guys im a little stumped right now. my boats an 18ft bass boat that weights 1060 pounds usually i run with myself and one other person, so with gear and loaded up i would say roughly 1700lbs. i have a mercury black max 150hp on there. when i originally bought the 150 it had a 23 pitch prop that had more of an big ear shaped blades. i ran it on the boat for a while but had a garbage holeshot and it was stainless steel. on average i hit 50-60mph depending on how much weight due to gas etc, this was at a 5600 rpm mark. now i have switched over to a turning point hustler prop which is a more aggressive style prop and is vented for holeshot. its also aluminum which i rather because i run in rocky lakes (canadian shield) so i rather the piece of mind if i somehow ever run on a rock, that the prop will be absorbing most of the damage. the holeshot is a ton better but now i have an rpm and rooster tail problem. basically im throwing a massive rooster tail way past my cowling but at low rpms, its hard for me to get past 5000 without porpoising. i understand that trimming out too much is causing my rooster tail problem but i have to trim out to get the rpms higher. im not entirely sure if my assumption is correct but heres my plan this weekend. im thinking that my jackplate is too low. i want to higher the jackplate 1/4 inch test and repeat. i feel that if i higher the jackplate i wont have to trim out nearly as much keeping the prop from wasting energy throwing water up but instead throw water back to push the boat forward. i think this would result in a smaller rooster tail as well as reduce raising the bow too much resulting in porpoising. as well as allow me to have higher rpms because in theory raising the jackplate allows for higher rpms. im by no means any professional (which is evident lmao) im just trying to learn and figure things out so any help or advice from experienced dudes out there will be greatly appreciated.
