⚙️ Key Features

• Serpentine-drive petrol-engine seawater pump
• Used across inline-four, V6 and V8 engine families
• Verified Johnson and JMP cross-references
• Flexible-impeller positive-displacement design
• Rebuild components remain serviceable

🔌 Function

The pump draws seawater through the intake and circulates it through the engine, heat exchanger, oil cooler and wet-exhaust system as applicable.

⚠️ Common Signs of Failure

• Reduced or intermittent exhaust-water discharge
• Missing, cracked or permanently set impeller vanes
• Seawater leakage from the shaft seal
• Bearing or pulley noise
• Scored cover plate or worn pump cam
• Loss of prime caused by air leakage or corrosion

🛠️ Service Notes

• Close the seacock before starting work, and make sure it is fully open again before the engine is started
• Never let the pump run dry — an impeller can be ruined in seconds without water, so fill the strainer or pour water into the pump housing to help it pick up prime after fitting
• Renew the O-rings, gaskets and hose clips on refitting, and check the hoses and strainer for perishing, softening and blockage while access is good
• Check drive belt condition and pulley alignment where the pump is belt driven, and turn the engine over by hand before starting to be sure nothing binds
• Start up and confirm a strong, steady discharge with the exhaust water, then check the pump body and joints for weeps and check again after the first proper run
