Transom Bellows Kit 30-803099T1 MerCruiser Alpha One Gen 2 with Gimbal Bearing
Transom Bellows Kit 30-803099T1 MerCruiser Alpha One Gen 2 with Gimbal Bearing
Product Overview
Transom bellows kit with gimbal bearing for Mercury MerCruiser Alpha One Gen 2 sterndrives from 1991 and newer. It replaces kit 30-803099T1, plus Sierra 18-8206-1, GLM 21960 and Mallory 9-72904. The kit contains the U-joint bellows, exhaust bellows, shift cable bellows, a gimbal bearing, a water intake hose and the outdrive gasket set, together with the clamps and rings needed to refit the drive. Fit it whenever the drive comes off for bellows, gimbal bearing or alignment work, since a split bellows puts water straight into the gimbal housing.
