I only see Air Seps on big Detroits, etc... all gas motors have to have a flame arrestor..
I've NEVER seen a K@N in a boat... but I don't work on many mastercrafts and such anymore.....
Not sure when they got away from the flame arrestor, but the last 2 have had metal closed end style K&N's on them.
The new one sorta make sense, as is fly by wire. But, the last one was MPFI, and no "flame arrestor" to speak of.
A 98 Malibu I used to work on had a metal flame arrestor with metal mesh surrounding it, but no real air filter to speak of.

Current Indmar 350.
