I'm swapping out a 1976 merc 115 with power tilt and trim and installing a 1980 merc 90hp that does not have power trim but it looks like it should fit right on the mounting brackets of the pwer trim, basicly I want to keep the pwr trim is this possible? also about how many men does it take to lift the 115 off the boat it seems pretty heavy. also the 90 has not been started in over 3 years but the owner hand turned the flywheel every year. he put oil in the cyl before he stored it. and I put oil in them myself and have let it sit for a week what else should I do before trying to start it? I have an impeller but that is all right now. what else should I pick up. also where can I post used engine parts for sale? the 115 still runs but cyl 3 is 0 compression. I know someone could use the parts. obviously e-bay but I was looking for something less formal. thanks
