Jeff,
That's an elegant solution but are you sure there isn't any positive
pressure in the heat exhanger that would force cooling water back thru the
PSS? Not sure it would matter but it might be a concern. I simply routed and
clamped a piece of 3/8" plastic tubing from the PSS barb to just below the
underside of the aft engine cover. It's several inches above the water line,
near the center of the boat and I've never seen any evidence that water
comes out of it.

Joe,
I removed the drain petcock at the aft end of the exhaust manifold heat
exchanger and replaced it with a brass barbed fitting. A hose connects that
to the barbed fitting on the PSS. The hole in the heat exchanger has metric
threads that are not quite identical to 1/4" NPT so I ran a 1/4" NPT tap
thru them (I think it was 1/4", but it was a few years ago) and then the
barbed fitting threaded correctly.
Here is a pic from the 320 site:

Good luck,

I recently installed the replacement to the PYI PSS shaft seal that is
vented. It requires that the vent hose be installed 2 ft above the
watereline. It is not obvious to me where I can run the vent hose to
achieve
the necessary height. Any suggestions would be welcomed.
Thanks,
