1979 prestolite trim pump

[BoatingIsNewToUs]

Recently bought a 1979 4 winns boat with a 115 hp mercury with power trim.
Fixed everthing up and our last time out the trim stuck in the up position.
Have tried re bleeding the lines but the down lines will not pump oil, the up lines pump a good stream of oil.

Any ideas on what to do?

Welcome,
I think you will get better results in the Merc section.
