I recently bought a 16' Lowe aluminum boat with this motor on it. I am getting it all tuned up and running and noticed there is no air filter or any kind of cover on the intake of the carb. I have noticed this on other outboards but I wanted to make sure that there isn't supposed to be one on this particular outboard. My main concern with this is the fact that the foam inside the engine cover is starting to deteriorate and I am concerned that some of that foam could get sucked into the carb.
