The holes on this are too large and it does not seal correctly. Avoid this product.

I needed these for my 92 Seadoo XP with yellow motor. I don't know why the gaskets are different between white and yellow motors but I just had to snip off the unneeded water jacket extensions on the gaskets that seal to the jugs. Otherwise they are a perfect fit.

These are cheaply made gaskets. The holes for the bolt are extra big, allowing for the gasket to move around and cover up the exhaust and coolant passages. I applied some glue to hold it still but the passages still don't line up correctly and only about half the gasket it sealing.

Had to order gaskets twice to just have enough gaskets to do the job. Because I was shipped 2 of the bigger gaskets and one small when there should of been 1 big gaskets and two small.
