This gear shift cable bellows for MerCruiser sterndrives is a flexible spare part that is mounted around the gear and shift cable at the drive. The bellows protects and seals the area around the moving cable.
The corrugated, conical design allows the bellows to follow the movements of the cable. The bellows is made of rubber and has a different diameter at each end. It measures 115 mm in length with a diameter of 6 mm at the narrow end and 35 mm at the wide end.
The gear shift cable bellows is used on MerCruiser sterndrives, including #1 and #2 drives, Alpha One Gen I, Alpha One Gen II, as well as Bravo I, Bravo II, and Bravo III. The cross-referenced spare part type is also used for MC-1, R/MR/Alpha One, Bravo X, Bravo XR, Bravo XZ, Blackhawk, and Vazer. Compatibility includes MerCruiser sterndrives with an internal gear shift cable from 1963 onwards, provided the relevant OEM number matches.
