⚙️ Key Features
- 0.236 kg
- Supersedes 831022
- 8 applications on AQ and BB series engines
- Raw water pump impeller
🔌 Function
Spins inside the pump body and sweeps water through it, so raw water is drawn in and pushed on through the cooling circuit.
⚠️ Common Signs of Failure
- Weak or no water flow at the exhaust outlet
- Temperature rising under load
- Vanes torn, cracked at the root or missing altogether
- Vane tips taken a set or gone glassy and hard
- Rubber fragments found in the heat exchanger inlet
🛠️ Service Notes
- Recover every missing vane from downstream, since a fragment lodged in the heat exchanger will keep the engine hot after the impeller is renewed
- Fit a new cover gasket or sealing ring at the same time, and never run the pump dry even briefly
- Seawater pump 831178 in this round is the complete pump if the body or wear plate is scored
