🔌 Function

The sea water pump impeller draws raw water from outside the vessel and circulates it through the engine cooling system. A correct impeller is essential for maintaining raw-water flow and preventing overheating in Bravo and inboard-style MerCruiser cooling systems.

Common signs of failure:

• Engine overheating

• Weak or reduced raw-water flow

• Overheating at idle or under load

• Cracked, curled or missing impeller blades

• Rubber fragments in the cooling system

• Pump squeal or dry-running damage

• Water flow not restored after impeller-only replacement due to worn housing components

📦 Condition

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
