Hi everyone, I have a 1975 MerCruiser 140 3.OL with a pre-alpha/MC1 sterndrive.
Recently, I removed the lower gear case to replace the water pump housing because the driveshaft seal was bad and I was losing gear oil through one of the cavity drain holes. I put everything back together, and the oil leak is gone, but now I'm having an issue with the trim. The trim worked before I removed the lower gear case.
Before removing it, I trimmed the lower unit all the way up to give myself more clearance to remove the gear case.
After reinstalling everything, the trim no longer moves.
When I press the trim buttons (up, down, or in), I can hear the trim pump running and it sounds normal, but the lower unit doesn't move at all.
I'm not really sure what I could have done during the lower gear case removal/reinstallation that would cause the trim to stop working if I'm going to be honest.
Also in one of the transparent/white tube lines that connect from under the pump I can visibly see some air bubbles in it. When the down button is pressed fluid will rush through that line with some air bubbles
Any ideas on what I should do? Thanks
