Hello I am a newbie to boating with inboards. I have a Alpha One Outdrive which is a new unit and first time in the water. I was boating yesterday and when I pulled the boat out of the water I heard the lower dragging on the ground. I am able to move the unit freely up and down by hand with no resistance with rams. The pump still sounds off when trimming up and down as well as the trailering button but does not move the lower unit of course. I understand I will have to find the leak souce and repair as well as adding 10w30 to the resevoir. My question is, Would this of damaged the pump as I was sill using the trim throughout the day thinking it was working, Or? And is there a special way to bleed this or is it self bleeding through the vent? Its very stormy right now and I would like to pick a couple brains for your input before I start this repair. " As a note there was no fluid leaked in the bildge compartment. I would appreciate some expertise on this as per my owners manual is very vague on the topic.
