That's what I have on mine. I usually run my boat pretty hard and only see a minute amount of vapor from the breather. I'm running a pretty big cam and in gear I only pull 4" of vacuum at idle so I don't want to try a PCV. My motor only has about 80 hours on it so it's still pretty tight. Has anyone tried extractors in a marine application? I know it's only worth a couple of hp on the top end but would certainly keep the bilge clean.

Anybody got photos of their puke tanks installed?
