I put a 90 hp on my boat with a stainless prop. when I trim up it stops at 5100rpm I can't trim up anymore question I have is, does this happen because of the prop degrees or does the motor have to be adjusted down or up more. My last motor I could trim up to the point it would come out and over tac. I can go 38 to 40mph down stream and 35 to 36 up. max rpm is 5500rpm I would like to get it closer to 5300 to 5400 rpm.
I hope you understand what I'm saying.
