⚠️ Common Signs of Failure

• Low seawater discharge
• Flexible-impeller vane damage
• Shaft-seal leakage
• Bearing or gear-drive noise
• Corroded pump body
• Water entering the drive section

🛠️ 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
