captpierre Posted August 28, 2015 Report Share Posted August 28, 2015 Just wondering. All my other engines have air filters Why don't outboards? Link to comment Share on other sites More sharing options...
Smokercrafty Posted August 28, 2015 Report Share Posted August 28, 2015 Water is usually a dust free environment ....... Outboards will sometimes have an air box in front of the carb though. Acts more like a resonator, than a filter medium. I have two identical outboards, one with, the other, without. Link to comment Share on other sites More sharing options...
dhickey Posted August 28, 2015 Report Share Posted August 28, 2015 Good question. I would think that the cowling around the engine is for the most part a sealed unit and it pulls air through ports on the back side closer to the prop shaft thus pulling clean damp air into the carbs. That would explain why marine oil is different than other types of engine oils. Link to comment Share on other sites More sharing options...
