Perfect ReplacementโMy SeaโDoo Starts Like New Again!
I couldnโt be happier with this Starter Solenoid Relay Replacement for my 2007 SeaโDoo RXP 215. Installation was straightforward, the fit was spotโon, and it immediately solved the intermittent starting issues Iโd been fighting with. The build quality feels solid and durable. After installing it, my SeaโDoo fired right up without hesitation and has been starting flawlessly ever since.

Perfect replacement
Purchased for my 06 Sea Doo that didnโt want to start, installed this new solenoid and it fired right up. Very happy and would buy again.

2006 Sea-Doo GTX
Just installed into my jet ski and it now fires right up. It's not in a fun location and the install was a bit of a pain.

This worked great for our jet ski. Who knew we needed this but the guy online said this was the problem and it was!

Bought 2, but 1 never worked
Bought 2 and 1 worked great. The other came with a broken housing (but it seemed like a manufacturing defect, not shipping damage).
