Onan MDKC & Onan MDKD Replacement Seawater Pump
Oberdorfer N202M-11, Onan 132-0277 replacement seawater pump.
Used on Onan MDKC (3.5 & 4.0kw) and Onan MDKD (6.5 & 8.0kw).
This pump is not a direct replacement but many customers have successfully replaced the Oberdorfer using it.
Dimensional differences are illustrated. The spigot on this pump is also smaller than the Oberdorfer so it will mount but will not have the same support with the spigot.
The replacement pump has inline hose connections. 90° hose tails are available here which are shown fitted in the last photograph. Add the hose tails to your cart should you require them. You will need to move your hose connections to fit the wider replacement pump with hose tails.
This is an Ancor pump AN 6576 ST 315.
