Bought this motor used late last summer, 50hp Merc 4 cylinder 500,blue band, serial 7007633. As boating season approaches and it's still quite cool here, what is the ideal cold start procedure (electric start, electric choke). I've noticed that when pushing the choke button the choke closes, but only while holding the button. I would assume that startup should be...move idle lever up, hold choke button down, crank, release choke button, allow to warm up?<br /><br />Thanks!
