    Default 1998 Moomba Carb information

    Hello,
    I have a 1998 Moomba Outback and am looking for some information about the Carburetor. I have a Indmar 5.7 engine with a 4 barrel Holly carb. I can't seem to find a model number on the carb. I did find a number but it doesn't seem to be good. I can't find the number on Google anyway. Anyone know how to look up the exact carb that came with my engine? I need to order the vacuum diaphram for the secondaries.

    Thanks

    If it is like my Pleasurecraft engine with a Holley carb, the number is specific to Moomba. My mechanic knew the cross reference number. There was one part that came in the rebuild kit that was not correct. I'm thinking it was a power valve or something like that.

    I have a '99 and had the same issue. Look on the front of the carb for a series of numbers. Then call Holley to match the power valves to the carb. The kit I ordered had the wrong valves, but I got a set on Ebay for $15. (Valves are 2.5) My carb is a 75021, chances are good yours is the same. Kit was $40
