Carbon Ring Kit for Sea-Doo GSI 720

This carbon ring kit is a driveline sealing assembly for the Sea-Doo GSI 720, sealing the driveshaft at the hull pass-through so water cannot enter the engine compartment.

Overview

This carbon ring kit for Sea-Doo GSI 720 personal watercraft replaces the worn sealing ring that rides against the driveshaft support. The carbon ring kit maintains a tight barrier at the through-hull point so the engine bay stays dry while the shaft spins freely. Owners and shops servicing the Sea-Doo GSI 720 will find this carbon ring kit an essential driveline wear item.

Good To Know
