As the flexible boot ages, cracks or splits, it allows water intrusion that can corrode and damage the U-joint, gimbal bearing, and coupler, so a cracked or hardened bellows should be replaced before it fails. This bellows is built by Sierra to fit specific MerCruiser drive applications by serial number range, and the correct part is confirmed by matching your drive model and serial number to the fitment listed below rather than by appearance alone.\u003c\/p\u003e\u003cp\u003eThe bellows is constructed of metal and finished in white, and it installs with the correct clamp for a secure, watertight seal; a matching 18-7316 clamp is included with this bellows. It is intended for MerCruiser #1 drive units without a ridge, serial number 3443920 and below, and is commonly used during routine bellows replacement service or when servicing the gimbal housing on applicable MerCruiser drives.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
