there no PCV on the boats you blow it in to the flame arrester so it not getting pull out so boat heads can get funky .so heat is the only way it burns out some may draw out of the vent tubes to the arrstor

I noticed that.

The motor has a air breather on the right valve cover. Think for future motor, it should be switched to both lines back to flame arrestor? Or you think the air breather is better? The arrestor does have hookup for 2 lines. It's set up where the line off the left valve cover tees off in both arrestor hookups.
