Just completed an engine/coupler re-install on my 470 mercuiser.<br /><br />Was wondering if there will be a need to bleed the trim/tilt lines or can I just top up the pump reservoir and it'll be OK? I'm sure they're full of air pockets given I had to disconnect to pull the engine.<br /><br />If I have to bleed do I simply disconnect/loosen all lines at each cylinder or what?
