    21I set up

    Hello I have seen a lot of things on set up. I have a 21 I with a 300. I am seeing 1-1/4 inch below the pad with good water presure. I see you need 2 1/2 below. I am runing 75@5400. I am 7 dimbles and 11/4 above the bolt on plate. water pressure is good. Yamaha prop 27 T-1 15 1/8. Im a little confused on this. thanks Jere

    I have the same boat but I have a hydraulic jack plate. The best speed I've ever had was 78.2, and that was empty on a nice cold day.

    I'd recommend some on the water testing and adjust your plate as high as you can without sacrificing water pressure, handling, or prop blow out coming out of the hole.

    Wish I had better scoop for you, but every hull is different, and the only way to get it dialed in is through experimentation.
