I'm replacing the tilt/trim motor on my old nissan outboard. My question is how do I bleed the system after it's installed? I don't see any bleed fittings like you would find on a brake system. Do I just keep filling the resevior while running it up and down? Do I try to pre-charge the ram before connecting the lines to the pump? Should I run the t/t motor or move the outboard up and down manually till the system is charged? Thanks in advance of any advise.
