Palmer 60 Marine Engines with
Oberdorfer Gear Drive Raw Water Pumps
Oberdorfer Gear Drive Water Pumps
Some early model Palmer M60 engines used a gear drive
Oberdorfer water pump. These pumps offered positive
displacement water flow rather than rubber impellers which
can allow water to slip past the impeller.
Oberdorfer Gear Pump Size
The pumps were small and would fit easily in the palm of
your hand. Aside from turning the grease cap once in a
while, they needed little maintanance. There was no
annual replacement of the impeller, because they did not
have one.
Oberdorfer Gear Pump Dis-assembled
There were very few parts to the gear pump, and it
functioned much like the engine oil pumps.
Oberdorfer Gear Pump Installation
The Gear Pump was installed with the discharge out the
top and the intake on the bottom using a typical flange
mount. These pumps were not self-priming, and work best
mounted below the waterline.
