    Default Transom adapter plates

    I'm building my own transom adapter, the plate i'm using for the main peice is 3/16" thick. I have about 3/16" or so clearance around the majority of the pump minus a few cuts for the jetaway ears and what not. I plan on making it modular so i can pull the pump easy. For the plates that bolt to this plate and press up against the pump how thick should they be? I have 1/8" aluminum, it seams fine but if i can get away with 1/16th i think it would look better.

    Shaun,
    1/8" is usually plenty. Here's a couple examples.
    This was the first version on my Bahner:



    The second and final was when I decided to go to Calgo steering:



    Lots of time with cardboard making templates. It would have been a lot easier if I had done the second one before the suction hsg. was powder coated.

    I've done 3/16, 1/4 & 3/8. IMO, 3/8 though heavier, is far superior when it comes to preventing leaks, though my boat is a 21 footer and probably sees a little more chop and therefore more stress on the transom. I keep the clearance as tight as possible around the suction housing. Hand hole is all the way outside.

    If your going that far, the AT kit has the reverse cable seal incorperated in it, available from your favorite vendor.
