I have a 26 trophy, and it spins at 61-6200, but will top out at 77 mph. Same motor height.

I have tried it above, and below. It seems to like even with pad, but I am puzzled with the low top speed.

I bought the PT 27, and its a bit faster but rpm's are way low. Any suggestions.

I have a sportmaster with 1.75 gears, water pressure is 12 to 14 psi.

Set back is 14"

Boat is 96, and motor is a 2001. Its bone stock, no mods.

Appreciate all your comments.
