Installation Notes
- Ensure the engine is off, cool, and the battery is disconnected. Close the seacock to prevent water ingress.
- Place a suitable container below the pump and drain the coolant from the system.
- Carefully loosen the hose clamps and remove the intake and outlet hoses from the pump. Note their orientation.
- Unbolt the old pump from its mounting bracket on the engine. It may require gentle persuasion to release if seated for a long time.
- Thoroughly clean the pump mounting surface on the engine, removing any old gasket material or sealant residue.
- Position the new gasket (if supplied) and mount the new pump, ensuring it is correctly aligned.
- Hand-tighten the mounting bolts, then torque them to the engine manufacturer’s specifications in a crossing pattern.
- Reconnect the intake and outlet hoses and secure them with the clamps.
- Refill the cooling system with the appropriate coolant.
- Open the seacock, reconnect the battery, and start the engine. Immediately check the pump and hose connections for any leaks.
Troubleshooting & FAQ
How do I confirm this pump fits my specific engine?
Verify your engine model matches one of the models listed in the "Engine & Model Compatibility" table, such as TAMD122A or TMD102A. Also, confirm your existing pump corresponds to one of the OEM part numbers like 3829313.
What makes this JMP pump different from the original OEM pump?
This JMP replacement pump is designed with several enhancements for longevity, including a heavy-duty cast housing and a modern mechanical seal, which provides greater durability compared to the traditional lip seal found in some original pumps.
What are the signs of a failing seawater pump?
Common symptoms of pump failure include engine overheating alarms, visible water leaks from the pump body or weep holes, a noticeable reduction in water flow from the exhaust, and grinding or squealing noises originating from the pump assembly during operation.
How often should the impeller inside the pump be replaced?
Impeller lifespan varies with use and water conditions. As a general rule, inspect the impeller annually and plan to replace it every 1-2 seasons or every 200-300 hours of engine operation to prevent unexpected failure.
Can I use original Volvo Penta parts to service this pump?
Yes, this pump is designed to be fully compatible with original Volvo Penta internal parts, allowing for flexible maintenance and repair options.
