Hydraulic Pump Oil Selection

[YoungStream]

What type of oil should I use to refill a trim pump that runs a jack plate?

Is there any special process for bleeding the lines?

Thanks,
Tim

I HAVE USED MERCURY TRIM OIL IN THE PAST WITH NO PROBLEMS.SINCE THERE ARE SO MANY DIFFERENT MANUFACTURERS OUT THERE BLEEDING CAN BE QUITE DIFFERENT FROM UNIT TO UNIT.POST UP WHAT YOU'VE GOT AND SOMEONE ON HERE WII KNOW.

It is the old style Merc hydraulic trim pump, the same type that would run the trim on the old Mercs with the external pump.

Thanks,

I DONT THINK THERE IS ANY DIFFERENCE BETWEEN THE OILS THEY USE FROM OLD TO NEW.
