why would you want a filter on it? not like your stirring up alot of dust on the lake
You're not stirring up a lot of dust on the concrete interstate (not like the 2.5 miles it takes me to get to pavement), why run one on your car?

There is the exact same dust, in the air over a lake or river, as there is over the shore next to the same body of water.

I run a K&N filter (14"er). After several years, it IS QUITE GREY/BLACK, all around, and not from "towing dust" since I run a hood/engine cover and very little "road dust" gets under my hood, let alone to the carb.

This is the same dust that went past the "flame arrestor", into the engine for 26 years before (dad bought Lowrider in 1978, showroom new, gave to me 2003).
My flame arrestor was $100, USCG legal (hooded engine again, "enclosed". K&N is a valid "flame arrestor", due to the metal screening. The USCG tops and bottoms, are stainless, not spun aluminum (the "off-road" cheapies).

No, nothing "missing".

Those stock flame arrestors are pretty restrictive, the small K&N unit will likely flow more air (slightly), a bigger one would do better.
I've never personally been a big "velocity stack" guy, but, they work OK with a filter on them. Without one, they actually can HURT since air flow over the front edge (from fwd motion) can be very disruptive to flow down the stack. Turbulence.

I'm running a K&N, 4" in an oval flanged assy. Covered engine with 2", removed pad insert and added the 4". It got dirty before and after.

Well I run an air filter on my car because all of the road dirt that the other cars in front of me are kicking up and the occasional dirt road i get on. when I ride my harley for a mile or two on the frewway I can feel the dirt on my face and wipe it off with a white towell and see it. When I ride in my boat across the lake and back I dont have any problems with dirt on my face so the way I see is there isnt much dirt out there over the water. I dont know maybe it has something to do with the lake ? and I always tow the boat with the intake scoop covered. Just seems like an added cost for nothing. I can understand in a covered motor or a scoop where flame arrestor is needed to be CG aproved

I run filters on everything I own or will ever own. Can't afford building my engine over again any time soon from a stray grain of sand or who knows what is flying around that river/lake air. I used to live in Needles, you couldn't imagine the amount of silt in the air out there.

Ive also been thinking about getting a K&N cleaner for my set up.. The issue i have is the scoop i run . I was told that i was SOL putting a filter on while using that scoop... :mad: My thought process being that a K&N should flow either as good or better than the USCG FA and also filter any particulate matter out of the air.. Better to have and not need then need and not have.


Little crooked in the pic but you get the idea...

Here in Kansas, there are times the air simply turns a faint shade of orange. ALL the air, in town, in the country, over the freeway, and OVER THE LAKE.

The south wind blowing Oklahoma north to Nebraska.

I don't FEEL the dirt on my face either, riding my bikes, or driving the boat.
I know darned good and well that it is there.

I've been to the desert SW where so many of these folks boat.
The wind blows that crap all over too, including OVER the water.

Don't run a filter if you don't want to joe, but don't deny the fact that the air contains small particulate matter (dirt) EVERYWHERE. A body of water does not "magnetically pull it out" somehow.

Now, 20 miles offshore over the ocean, maybe. A waterway of ANY size in the nation itself, dirt is in the air over it just like on shore.

The only reason boat engines don;'t show wear from it is the lack of running hours.

My boat gets between 40 and 80 running hours a year most years.
My truck gets 32 hours a MONTH, MINIMUM, x12, just to and from work.

A year of my truck is a decade on my boat.

barbon flame arrestors are ALOT more restrictive than that k&n. i have two "slightly modified" barbon's on the sw. when i got the boat, i went to the parts joint, got the k&n book, and hunted through it until i could find some filters that were the same id/height as the barbon's od/height. been using them ever since. c/g can't say i don't have a flame arrestor, sez so in plain sight. they're just sealed pretty well inside k&n's.
there's a lot of dirt in the air, no matter where you are. the 2 k&ns get dirtier than the k&n on my truck, so i clean and recharge them at least once a year... no gnats in my carbs, they're always clean...

Thats what im thinking it must be the area because it sure seems clean enough to me where i boat. and smokin I said that i DO get dirt on my face when riding my motorcycle on the highway and would always have an air filter on the street. but on the lake it just doesnt happen at least where I boat. and you are right about the hours put on it are minimal hence no signs of wear from it so Id rather run un restrricted if possible. but if a covered motor and a pcv valve or a breather tube blowing all that oil vapor around then yes it will turn a filter black and make it look dirty. there is alot of stock mercrusers and omc marine engins that only run a flame arestor and that wont filter out dirt but the factory sells the engine with it on and no filter? Im not saying its ok to run dirt in your motor if the air is dirty filter it but thats the difference in locations. kinda crazy though to say california (where I boat) has clean air LOL
