Thanks for your replies. So..i should reach full speed with no trim and then start to bump it up slowly until i feel it start to chine and then bump it down slightly to reduce or eliminate the chine.? From here, should this be the max speed of my boat with its current setup? If Im only getting 5500 rpm on an Opti (when the max is 5750) should i then tinker with raising it slightly on the jack plate?These maybe be novice questions…but that what i am. Thx guys.
