    Alumacraft MV1448 Seadoo IB jet, Still jetting

    I would like to see how the engine cover turned out. I cut my spoon off. I decided (per your advice)to angle cut the center rib down in the back (sloping towards pump) and welded it up. I am through messing with it for this year. Time to fish !! Next year I may try the spoon again out of UHMW...

    I gave it a shot tonight in some pretty good chop. Not good. heavy cavitation. Almost seems worse than before. :cry: I will try it again when it is calmer and see what happens.

    I have a Hobart 135 that I can kind of weld aluminum with. Otherwise I bought some braizing rods I am going to try. I will give it a shot in the spring and see if it helps. Where did you come up with the spoon design ? Thanks !!

    That is sweet !! I have a 16 x 48 with a 650 kawi and a tigershark pump. I am having some problems with cavitation unless the water is pretty flat. Do you think the revised intake helped more or do you think the spoon is the hot ticket ?? Thanks Steve

    Hear is all I have for pictures. The steering is from a kawi stand up which I modified and the throttle is from a snowmobile. The throttle cable is from a tandem bike rear brake.
