WSM Tigershark 640 647 Piston Kit STD Size | 010-850K For '94-'99 PWC

Got an old Tigershark jet ski?

This is a piston kit for the 640 and 647 models, from about '94 to '99.

It's the STD SIZE, so standard bore, not oversized.

Made by WSM, which is a good aftermarket brand for PWC stuff.

The part number is 010-850K.

Comes brand new in the box.

If you're rebuilding that old 2-stroke engine, this is what you need.

Just make sure your cylinders are still good to go for standard size.
