I recently had to replace my trim/tilt reservoir (actually I have it ordered now). It is one of the older Oildyne that uses the 1 bolt that attches to the bottom of the pump. I guess the thing had been cracked for a while. Anyway, I went ahead and removed it today. My question is, can I just replace the reservoir, add oil and it work? I'm thinking that I'm going to have to 'bleed' it somehow to get the air out of it? Any info I could acquire on this would be greatfully appreciated.
