Hi guys I have and old cmc hydraulic jackplate it has the electric pump mounted to the outside of the jack plate and the pump is shot does anyone know we're I could find a replacement pump or retro fit a different pump on there

Can it be rebuilt or is it destroyed?

Last time I checked CMC weren't very forthcoming with parts, they just want to sell new assemblies for Big $$.
Could be that an outside hydraulics supplier can help.

Try contacting Bob's Machine Shop in Florida. They sell a motor/pump assembly that is used on their Jack Plates. It is a hydraulic pump and the pressure is adjustable on both the in and out travel on the cylinder. In you case, up and down.

I replaced the motor on mine last summer. I took it to where they repair alternators and starters, he couldn't fix it so he ordered one from one of the companies he deals with. Pricey though, $325 tax incl. and that's with no pump.

There the same pump as the older external mount omc pumps i believe. Atleast thats what my buddys was. Just need to find one off an old omc and ur set if thats the case

The Bobs pump is the same as a Merc trim pump and the merc trim hosed work also. I have the same setup on my AE. You also end up with a plate that cycles up and down allot faster . Make sure the rest of your plate is in good shape, some of them elongated around the slots on the side.

Sorry for the late response but I got it rebuilt at my local electric motor shop for 90 bucks and mine did have 2 messed up slide holes in just die grinder it a little bit now the slides work good should I be concerned about that

if the plate has play in it yes , post a pic if you can
