Re: 1988 REVENGE 22 Walk-Through

The drain openings in the cockpit deck drain into the rigging tunnels, as far as I can tell.

Buy some pink marine antifreeze and pour a cup into the drain. Find where it comes out to confirm the path of flow.

Re: Dauntless 16 Engine Mounting Height, Propeller Pitch

I doubt hub vents will be useful on the boat and engine under discussion. Hub vents might be useful on a 75-MPH boat turning a 25-inch pitch propeller.
