    I'm not mechanically inclined but four years ago I had a semi-retired boat mechanic help me with my carb. I took it off and got the numbers on the carb that were Moomba numbers by Holley. The rebuild kits no longer list that number and the mechanic cross referenced to a kit available What he did? I don't know but he mentioned that marine carbs have different set ups than what that kit had so there were some modifications done. You need to find someone that can get you the right kit. It was easy for him but I don't have a clue where he got the kit. It works well is all I can say.

    Holey has the parts, but you have to call them directly. They don't have a kit, you'll order everything speratly. No one else sells the kits.

    I saw the same numbers on mine, but can't find a rebuild kit that matches. I will call Holley......Thanks

    I ordered the Holley 703-45 rebuild kit on Amazon. It came with some extra parts and the wrong power valves, but everything else worked.

    I also remember on my rebuild the mechanic mentioned something about the power valve in the kit being incorrect for this carburetor.

    Yes the correct power valve is the 2.5 not the 5.0 it comes with. World of difference in performance.
