  All MCM sterndrives utilizing a drive unit shaft cable (1963 & newer)

A shift cable bellows might not be the most noticeable part of your sterndrive, but it plays a critical role in keeping water out and ensuring smooth, reliable shifting. The Mercury MerCruiser Shift Cable Bellows (74639A2) is designed to protect your shift cable from moisture, debris, and wear, extending the life of your sterndrive system.

Built from durable, marine-grade rubber, this bellows is flexible enough to handle the constant movement of the shift cable while maintaining a secure, watertight seal. Its ribbed design enhances flexibility and durability, allowing it to withstand the harsh marine environment without cracking or deteriorating prematurely. It’s a direct OEM replacement, ensuring a precise fit for all MerCruiser sterndrives that use a drive unit shift cable, including Alpha and Bravo models.

Why It’s Essential:

• Prevents Water Intrusion – Keeps moisture out, protecting your sterndrive’s shifting components.
• Extends Shift Cable Life – Reduces exposure to salt, debris, and wear.
• OEM Fit & Quality – Designed specifically for MerCruiser sterndrives for hassle-free installation.
• Includes Clamps – Comes with hose clamps for a secure, leak-free connection.

A damaged or leaking shift cable bellows can lead to stiff shifting, corrosion, and even costly repairs. Replacing it with a genuine MerCruiser part ensures smooth operation and long-lasting protection, keeping you out on the water with confidence.
