Need a water pump for a Palmer P-60 raw water cooled model. Exact year unknown, but guess early to mid 70's |

Whats the serial no. of the engine. Is the pump a Jabsco or Sherwood? Sure you need the pump and not just the rubber impellor?? |

Richard,
Thanks again for your response, you are always "on top" of it in here.
I have no idea where to find the serial number on this motor.
And I am rather confident that I will need a totally new pump as it is leaking badly from the edges, and all over basically.
Can some sort of electric pump be rigged to give proper flow volume, if I cant find a new/rebuilt pump?
Thanks and I hope all is well for you.

Bob the following photos are the three different water pumps I know of for the M-60 AKA P-60. The gear pump dates back to 1955 when the M-60 was released for sale by Palmer. They later in the 1960s changed the name from M-60 to P-60. The gear pump is not a likely candidate for your engine I expect. The other 2 pumps are Jabsco or Sherwood they are most likely the version you have. You should note the different pump impellor drive tangs so you get the right replacement. I don’t understand why you seem to have water coming out from under the cover unless the screws are loose or a piece of the thin paper gasket has blown out due to a blockage in the water flow through the piping engine block and out the exhaust pipe. One of the advantages of rubber impellor pumps is they typically don’t build up dangerously high pressures on the discharge side which can do real damage to a weak place in the discharge side of the system.
You could hook up dock water to the hose feeding the engine block but don’t turn on the water if the engine is not running Start the engine and then slowly turn on the water and check water is being discharged out the exhaust pipe. Take it easy on the volume of water. Turn off the water and then shut down the engine within about 30 seconds so the engine can clear any water out of the exhaust side of the system. You don’t want to force water into the combustion chambers because there is no exhaust pressure being developed. If you should get water into the combustion chambers pull the plugs and crank the engine to blow out any excess and then start the engine without forcing any more water in and let is run for 30 seconds to clear itself. No big deal!!!!
The typical place for the serial number of the Palmer manufactured P-60 is either on the top of the flywheel shroud or on the brass name plate attached to the exhaust manifold. The reason I say Palmer manufactured P-60s is in 1971 Palmer went out of business and sold the P-60 along with several other designs to Thermo Electron AKA Crusader who made the P-60 for some years. I don’t know how many years but there apparently are a lot of P-60s still around.
Hope this helps. Dick

Don't know what I am doing wrong. Why is the text so wide and why didn't the second photo remain connected to the first message? |

Richard,
THANKS
The winner is door number 3 (AKA the Sherwood). I ran engine with both raw feed and input fresh from my flush line and at this time the output is "normal" for what I am used to.
Pump is leaking around outside edge and on the side where the mounting flange is...pretty good flow. I wonder how long bearings will last.
Now where do I find a Sherwood pump in PRISTINE condition? And delivered and installed for $50.00 ?????????????????
Thanks,
and where do I send the 6 pack?

Bob this is not 1950!!! A pristine pump if it could be found would be more likly $350.00 plus $150.00 yard mechanic time. Seems to me if the water is actualy around the mounting flange where it bolts to the engine you have a faulty seal on the pump shaft and the ball bearings in the housing must be messed up and water has been getting into the engine crankcase via the pump/distributor and alternator drive. It also suggests the water weep hole on the lower side of the pump must be plugged. The weep hole is intended to keep water from being pumped into the engine in case of seal leakage. My advice to you is to rebuild it yourself if you cannot find a good replacement. It aint Rocket Science!!! Just go to a bearing a seal dealer and have them match the existing seal and bearing. Don't talk Palmer, P-60 Sherwood. The dealer will want the seal and bearing numbers. |
