K&N Flame Arrestor

[brutustitan]

I'm about to purchase a K&N flame arrestor,<br />#692-59-3370.<br />It is 6 3/4" height x 9" diameter.<br />I just recently read on another website forum that this one isn't stamped, coast guard approved.<br />(I'm assuming because of the height)<br />Another guy says all K&N's are approved beginning<br />Jan. 04.<br />What's going on?

Hello, You need to know if it is USCG approved before you buy. If it is not it has no place in your engine room. The flame arrestor is exactly that, if this function is compromised when you need it most you may loose more than your boat. It could cost you your life. The best thing to do would be to contact K&N directly and ask them if this model is Coast Guard approved for use on boats. They should have a tech line or a website that you can use to get your answer.

Re: K&N Flame Arrestor

years ago i bought a stearns flotation coverall for less than 1/2 price because the cg had decided they were now a legal class 3 or 4 pfd. IF they had the cg approval label sewn into them. the ones on the rack without the label were discounted 50% and i have to carry a legal pfd with me when ever i wear them. the flame arrestor may be the same story. exactly the same minus the approval stamp and hence not legal. or not.

Re: K&N Flame Arrestor

Personally I don't see a need for a K&N.There is not a bunch of dust out in the middle of the lake that is going to enter your engine through your current spark arrestor.Which flows more air a piece of wire mesh or cotton gauze encased in wire mesh?The other thing is the fire hazard that a K&N presents.A normal spark arrestor does not have any fuel on it to burn when the engine backfires through the carb,but when you install a K&N you are adding alot of cotton gauze for the backfiring gasoline to cling to and start burning outside the carb.Just my thoughts Good Luck in whatever you decide.

It doesn't really have anything to do with dust, it's airflow.<br />Most K&N's will flow a lot more CFM than stock merc flame arresters.<br />The gauze will NOT burn - it's covered with wire mesh. Try it sometime....it's high school science.
