Good To Know

Q: What does a drive shaft bellow kit do? A: It seals the driveshaft passage through the hull, keeping water out while allowing the shaft to flex and spin. A torn bellow can let water into the hull and should be replaced promptly.

Q: How do I know if the bellow needs replacing? A: Look for cracks, tears, or a loose fit on the driveshaft, plus any water collecting in the hull near the shaft tunnel. Confirm your year and model before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
