Hi all, I'm just about to put my boat back in the water after a long cold winter. Had the engine "winterized" (lower unit oil changed, engine fogged, stabilizer added etc.) and am now wondering if I have to have it "summerized" before I put it back in. I really would rather not haul it back to the marina (which is what I usually due, hence my ignorance) and am wondering what exactly I have to do to get it going. Is it just a matter of gassing it up? Its a '75 Merc 1150. Thanks!
