    Water tube

    Is there a water tube designed for the short pump setup with the addition of a 4* wedge? The stock one would be too short, and the wedge is usually used with the extended pump. Am I doing something strange or am I just missing something?

    I was told to pull the water tube off of the hull, and put something to act as a gasket and space the tube out from the hull;this will make up the difference.

    If you don't already have the wedge, Randy's latest batch of wedges were cleverly designed thinner than the stock 4 wedge at the top, so that even though it was a 6 wedge, it didn't space the pump out any more than stock. I love smart designs like that!

    I think Delegem's idea is the only one that works.

    Hot Seat used to sell longer bolts with a wedge, but never mentioned about the tube.


    You may not want the 4* wedge J. They tend to make the ski leap out of the water under a hard accel without trim.

    It will also make porpoising more noticeable on a 2 seater in rougher water.

    With no wedge, the ski just launches forward, not up.

    It would help to gain some top speed though.

    Using a wedge on an SL hull without a longer ride plate or trim could create a porpoising situation

    Yeah, I should just try it without the wedge first. Porpoising is not a very efficient way to ride. I will have to wait until I get it all dialed in without the wedge before I try it with the wedge.

    Just use the extended pump and the longer ride plate. Problem solved. I have a 4 inch extention if you need one.

    I would need the extension, water tube, and driveshaft. I am planning on the extended Ocean Pro 'Ocean' ride plate, so that would be okay. Just not too sure if I want to extend the pump yet.

    I had longer bolts for one ski, but on my other (750) I went to the local hardware store and got a 3' piece of 3/8-16 (I think) threaded stainless rod. Cut 4 chunks to length, some stainless washers and lock nuts, and you're good to go!

    The steering and trim cables were a little harder, but I used some 10-24 threaded rod, stainless (had to order that from mcmaster) and some 10-24 coupling nuts. Worked good. make sure to always get highest grade stainless you can find.
