    Default Intake Setback

    I did a search and can't find the answer, so here it goes.

    How do you determine how far back to set back the intake? Is there a rule of thumb?

    Thanks,

    Setting the intake back has to do with alot of factors, And one of them is who and how the boat is being set-up, What type of hull it is, What type of hardware you are gonna use. Some people like the hand hole outside the transom and some dont.

    Greg , I am By no means an authority on Pump setbacks, But what determined how far back for me was 1) I wanted the handhole outside the transom and 2) All of My research lead to the understanding that I wanted the biting edge of the shoe as close to the back edge of the keel at the transom ,as I could get it, without going past. Just to clarify ,there are some who intentionally set the shoes bitting edge further back than the edge of the transom.
    I did talk with Jack McClure on the subject and that is where He had sugested....Hal

    If your not on the edge.......your taking up too much room......Drive it like you stole it!

    The intakes can be machined, to allow a farther set-back without cutting the transom.
