Troubleshooting & FAQ
How do I know if this pump fits my engine?
Check the 'Engine & Model Compatibility' table. This pump fits specific Volvo Penta TAMD162, TAMD163, and TAMD165 series engines. Verify your model number against the list. It replaces OEM part numbers 3837935 and 3825493.
What are the differences between this aftermarket pump and the OEM version?
This JMP aftermarket pump features several improvements, such as a modified cam screw, a gasket for the cam and end cover, and an O-ring for the cover. Due to these design changes, internal components are not interchangeable with original OEM parts.
What are the signs of a failing seawater pump?
Common signs include engine overheating, reduced water flow from the exhaust, visible water leaks from the pump housing or weep holes, and unusual grinding or squealing noises from the pump area while the engine is running.
How often should the impeller be replaced?
The impeller is a critical wear item. We recommend inspecting it annually and replacing it every 1-2 years as part of preventative maintenance, or immediately if you notice signs of reduced cooling performance. The replacement impeller for this pump is part number JMP 8301-01K.
Can I use parts from my old Volvo Penta pump to repair this one?
No. The internal components of this aftermarket pump are not designed to be interchangeable with original OEM pump parts. Always use the correct replacement parts designed for this specific model to ensure proper function and avoid damage.
Is installation difficult?
Installation is a direct bolt-on process for a mechanically inclined person. However, working with marine cooling systems requires care to prevent leaks and ensure proper engine cooling. We strongly recommend professional installation if you are not experienced with marine engine maintenance.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
