*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!

Note that as is the case with your local dealer, there is no warranty on new or used electrical parts purchased from us. The reason is that we buy electrical parts with no warranty from our supplier so can't return one no matter what the situation. Since you're ultimately the one who wants to get back on the water, you assume all risk for purchasing a replacement part and agree you will not hold us responsible if it doesn't work or doesn't fix your particular problem. All electrical parts are thoroughly tested at the factory before being shipped to us so they should be in proper working condition when you receive one. We sell lots of electrical parts with few complaints but part failures do rarely occasionally happen so keep that in mind when considering a replacement part. Finally, you'll need to make sure all other electrical components are in proper working condition BEFORE installing a replacement part.

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!
