Engineered Marine Products 61-01998 U-Joint Bellows for MerCruiser Stern Drives

The Engineered Marine Products 61-01998 U-Joint Bellows is a critical stern drive component designed to protect the universal joint in MerCruiser stern drive systems. This marine-grade rubber bellows creates a flexible, watertight seal that prevents water intrusion into the gimbal housing while accommodating the movement of the drive unit during operation.

Key Features:

• Manufactured from durable, marine-grade rubber material resistant to saltwater, oil, and fuel
• Flexible corrugated design allows full range of motion for steering and trim adjustment
• Prevents water, debris, and contaminants from entering the gimbal housing
• Direct replacement bellows for select MerCruiser stern drive applications
• Includes clamp for secure installation

U-joint bellows are a critical maintenance item that should be inspected regularly and replaced at the first sign of cracking, dry rot, or damage. A failed u-joint bellows can allow water to enter the boat through the transom assembly, potentially causing severe damage to the gimbal bearing, universal joints, and even flooding the bilge. Professional installation with proper bellows adhesive is recommended for a reliable, long-lasting seal.
