*PARTS SEARCH*

We don't have a way for you to look up oem parts yet but you can use the parts search HERE to get part numbers then use the OSD search to see if we have what you need. If the part doesn't show contact us and we'll add any parts not listed to our site (if not discontinued).
If a part shows "0" in stock...
When searching our site, you may notice out of stock parts. Parts not in big demand aren't kept on hand but we can usually get any out of stock item in quick. On our OSD parts (will have OSD in the title) and aftermarket parts we can usually have those here in 2-3 days once ordered. On most OEM parts those take about a week to get in. If you want one disregard any "0" quantities and order for quick service!

Add to Cart:
Over the years and various carb rebuilds, parts in your carb often get swapped out with parts that don't belong in them. We decided to fix that issue with these "Back To OEM" kits. What this complete carb rebuild package will basically do is bring your carb back to how it came from the factory. The package we offer features OEM Mikuni parts instead of aftermarket since if you want your carb back to OEM specs it needs OEM parts! The best feature of all though with this kit is you don't have to set popoff with this one since you're basically bring your carbs back to how they were when new. Sea Doo never messed with popoff and you shouldn't have to either!

  • Includes all OEM Mikuni soft and hard parts to rebuild your dual carbs including internal filters, gaskets, formed o-rings and more.
  • Includes Two (2) NEW 1.5 OEM MIKUNI Coated VITON Needle Valve Assemblies.
    Viton is the best needle you can use and resists the alcohol in todays fuels and these most current Coated ones resist fuel additives that can cause needles to stick.
  • Includes Two (2) OEM Mikuni Needle Arm Springs.
  • Includes OEM Needle Arms and Pins.
  • Includes Two (2) Carb Base Gaskets.
  • Also as an added bonus we include NEW Stainless Hex Cap Screws to replace oem slotted ones!*

TECH TIP...
If you're installing an impeller on a Sea Doo, don't follow the manual when it calls for red loctite on the threads... use anti-sieze instead. That way if you want to take it apart again you can. We've built hundreds of pumps now with anti-seize and it works great!
