Drive Shaft Bellow (High Tension) for Sea-Doo GS 720

This high tension drive shaft bellow is a replacement rubber boot that seals the drive shaft tunnel on 1997 to 1999 Sea-Doo GS 720 watercraft, keeping water out and grease in at the through-hull joint.

Overview

This drive shaft bellow (high tension) is a direct replacement boot for the drive line on the Sea-Doo GS 720 produced from 1997 through 1999. It seals the driveshaft passage at the hull, protecting the bearing and coupling area from water intrusion and keeping lubricant where it belongs. A practical service part for riders maintaining their own personal watercraft.

Good To Know

Q: Why does a driveshaft bellow matter? A: The bellow seals the driveshaft passage through the hull, so a torn or hardened boot lets water reach the bearing and coupling area. Replacing it early helps prevent corrosion and driveline wear.

Q: How do I know if my bellow needs replacing? A: Check for cracks, stiffness, or grease weeping around the driveshaft tunnel during routine inspections. If the rubber no longer flexes cleanly, it is due for replacement.

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