captpierre Posted August 28, 2015 Report Posted August 28, 2015 Just wondering. All my other engines have air filters Why don't outboards?
Smokercrafty Posted August 28, 2015 Report 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.
dhickey Posted August 28, 2015 Report 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.
irishfield Posted August 28, 2015 Report Posted August 28, 2015 Mine does... but really if you're boating in a dust storm you're on the wrong lake!
Mister G Posted August 29, 2015 Report Posted August 29, 2015 Lots of bugs that a outboard can suck in.......good question and something to think about.....are there any marine mechanics on this board ? ? ?

2 tone z71 Posted August 29, 2015 Report Posted August 29, 2015 Is your cowl not sealed and watertight ...where are the bugs gonna come from ?
glen Posted August 29, 2015 Report Posted August 29, 2015 I cover mine on dusty roads. Bugs won't hurt. That's just lube.
grimsbylander Posted August 29, 2015 Report Posted August 29, 2015 I have a cover on mine 100% of the time when trailering.
John Bacon Posted August 29, 2015 Report Posted August 29, 2015 Is your cowl not sealed and watertight ...where are the bugs gonna come from ? The engine wouldn't work if it was.
