Spark arrester

[William White]

Always wondered if the spark arrester (yes, not air filter) restricts air intake/engine rpm/top speed. I took mine off 350 mag and was surprised to see it runs 44 mph with it on or off on 2010 SeaRay 260 sundeck.

There should be little to no restriction, as it is just basically a baffle. Just take it off and clean with carb cleaner or another de-greaser (I use Simple Green) ever year, or sooner if it gets gunked up from engine breather gasses.

My heavy breather 7.4 sees no restriction, either.

Agreed with @Bill Curtis

Interesting, I never would have bet that.
