Dripless stuffing box vent tube location

[Project_Mayhem]

Where would you mount the tube for a PSS dripless seal? My options seem to be on the port side just below deck level or inside the galley cabinet closer to the centerline?

Port side: The port side is higher except for when healing. The head intake through hull is in this location. I love heeling so the rail does get buried sometimes

Galley cabinet: The sink will dip below the waterline on occasion in heavier waves. The sink has never overflowed so it seems to reason that just below the countertop would work

Waterline is approximately where the blue line is

I designed a crude catch can in the unlikely event that the vent tube overflows. It has an attachment for a drain tube.

What's wrong with in the engine compartment above the waterline? That's where I've always located mine? In freshwater, there isn't a need for any catchment device, the only time water will back up through the hose is under reverse at a high rpm. Any water that gets through willl simply evaporate.

Or, get a Hy-Vent (amazon link). These work well. The PSS folks sell them too at a premium.

The bottom of the sink in the countertop is below the waterline in heavy waves. I had water occasionally coming up the drain before in installed a check valve. The top of the engine compartment is at the waterline.

Do the HyVent's prevent air from escaping if the float valve inside is already floating? IE the waterline is above the device

Well maybe.Thats where mine was originally installed. And every time the engine was put in reverse the water would shoot up at least a foot up out of the tube soaking everything including the engine and all the wiring in the engine compartment. There was no possible way that much water would evaporate.
The solution was to extend the vent up to a new through hull that was installed in the topsides just below the rub rail

It has to be above the waterline.

Every potential spot inside dips below the waterline it seems. I can either mount it centerline 18" above standing waterline or on the port side of the hull 3' above standing waterline. I'm leaning more towards centerline.
