PSS and Vent Hose Location

I've been considering installing a PSS shaft seal before launch. I know quite a few PSC owners have them and I was looking for ideas. Where did you locate the vent hose? Is it possible to get to the stern locker?



Also, did you find there was sufficient room to slide the shaft back for the coupler without removing the prop?

Steve:

You don't necessarily need a vent hose if you remember to "burp" the coupling after a haulout. A low speed PSS coupling doesn't generally need one, although there is some debate about it.

I just got a PSS and didn't add a vent hose.

That's strange. I put one in a few years ago and was told they stopped making the shaft seals without the hose.

Just run the vent hose up as high as you can above the waterline.

I'd put in the wet locker along with the raw water loop.

I just received my PSS shaft seal and have been reviewing the installation instructions.

Step 15 plumbing the system:
note: sailboats or displacement powerboats with powering speeds below 12 knots can use either method A or B. However, displacement boats with a bearing in the shaft log must plumb water to the seal

Pacific Seacrafts have a bearing in the shaft log. Water must be plumbed to the seal according to the instructions. If there is no bearing in the shaft log then all that is needed is a vent hose above the waterline.

What method was used in the boats that have a PSS shaft seal with a bearing in the shaft log??
