I am trying to locate the air intake for my Merc 7.5 Electric Start 1984 outboard??? In hanging over the transom I can remove the "hood", but only see lots of metal and things! I am not an "engine guy". I can't see where to spray the "instant start" when there is trouble trying to start up after sailing? Any clues??..Looking down at the engine, is the intake forward, aft, port, starboard, stern quarter...etc??? Help from anyone would be appreciated!! I can just spray in the general area!
