I have a OMC trim pump that I wonder what the proper up and down trim pressure should be. I think the assembly is refered to as the Permanent magnet type electric motor with a reverseing relays that are attached to the unit. The pump has been rebuild by a hydralic company. How ever the up pressure is only 1400 psi and down 800 psi. This pump assembly was used on the smaller outboards 2 cylinder models 55 hp and down... any infor would be helpful... I reading information that says the unit should have 2000 pounds....thanks
