    Yeah I'm going to take carbs off tom. And rebuild them. Is rebuilding the carbs the same as rebuilding a four wheeler or dirt bike, I've never really messed with boat motors. Thanks Cray and Scrapper.

    Yes, they are very similar. Not hard. Just three of them instead of one. I do recommend getting a (oem) manual so you can link and synchronize the carbs correctly. You can get them online. Or just google it. You can find the process all over. But I do recommend the manual. What synchronizing will do is put all three carbs opening at the same time, and having the idle air right on all three. You will also set the timing when you do this. Its not hard. Just takes a little time.

    Take your time, be very particular with your cleaning. Then make sure you put the water/fuel sep on it before firing it back up.

    Let us know if you need anything.

    There will be a procedure in your manual called Link & Sync. This sets all your linkage and timing so they work properly. It is very important that it is done in the order given in the manual.
