Sierra 18-3349 Water Pump Housing Kit for OMC Cobra Drives 2.3, 2.5, 3.0, 4.3, 4.6, 5.0, 5.7, 5.8, 7.5

The Sierra 18-3349 Water Pump Housing Kit is a replacement water pump housing built for OMC Cobra sterndrive units. This kit supplies the housing component of the raw water cooling system, which circulates water through the drive to keep the engine running at proper operating temperature. The housing is made of rubber, which provides a durable, flexible seal against the mounting surfaces of the drive and helps resist the wear that raw water cooling systems place on pump components over time.

This kit is designed to fit all OMC Cobra Drives across a wide engine range, covering 2.3, 2.5, 3.0, 4.3, 4.6, 5.0, 5.7, 5.8, and 7.5 configurations with the specific model years listed below. Boat owners running these OMC Cobra drive setups can use this housing kit as part of a routine water pump service or when replacing a worn or damaged housing. Installing a proper-fitting housing is an important step in keeping the cooling system sealed and functioning correctly, which protects the engine from overheating.

The kit weighs 0.61 pounds and ships as a single unit under UPC 808282180423.
