OSD Sea Doo DESS Post Assy #2 (REPL 278000646 / 278000830)

Starting at: $59.99

Now offered are switch assemblies we personally build form high quality components to the same specs as oem Sea Doo parts. Additionally, the terminals aren’t just crimped but soldered then crimped for the best electrical conductivity and corrosion resistance you’ll find. In the environments these are exposed to, you want the best so that’s what we offer!

This is a complete Sea Doo DESS Post Switch to fit the models listed below. It includes a new plug that hasn’t been installed yet so if your application requires the wires to be run through, all you have to do is put the wires through the grommet then install the plug and you’re back in business. Just make sure to match the wire colors to the other connector when installing the plug!

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.
