Yamaha 1.8 Bov Kit

$ 200.00

The Yamaha 1.8 water craft is known for stripping supercharger teeth, and clutch failure. Our blow off valve kit will drastically improve the life of your supercharger. This is a great upgrade for stock to highly modified machines. The blow off valve kit bleeds the boost pressure off when you release the throttle, this eliminates any pressure spike that can rapidly stall the supercharger causing harmful damage.
