Anyone have experience with these? I've had this boat a little while now and on my last one I would get no water in the bilge, even on a busy weekend (mercruiser) while on this one the shaft drip lets water into the boat, not alot but it still sloshes around and gets down into palces where noone's ever been before and can corrode. On a busy weekend it can get a good amount and the pump only takes out so much. This says does not leak water into the bilge. Anyone have this? or experience with it? Thanks :D

PSS Shaft Seal. The PSS shaft seal is a replacement system for stuffing boxes. The PSS has no packing to adjust or replace and does not leak water into the bilge. Additionally, due to the simple design, the PSS requires no maintenance and will provide years of trouble-free service.

Yup, I put one of those on a boat I owned many years ago. It worked great to seal the drive shaft. That boat would still let a little water in through the rudder port however. I wonder if this is your source as well?

Like I said it's not alot but none is definetly better. So they do a good seal job on the shaft? that's good to hear. :D

Have you looked at the XPC SHAFT SEAL Ski Dim part #21705? Less expensive, easier install, no graphite and is standard equipement on many tow boats?

I agree on the XPC. It is especially nice, because it requires less room on the shaft to install, than the PSS.

Yup, I agree. I put the XPC on my present ride just last summer. It was way easier to install than what I remember from installing the PSS design. I like how the color matches my engine too.

This is what I get with that # at skidim, is this it? This says dual graphite :confused:

Dual graphite lip seals can be run without the water supply kit. Minimun free length of shaft needed for installation is 7".

Have you tried to adjust your packing? If it still leaks, replacing and then adjusting the packing should do the trick. You might also try greasing the fitting for the rudder, that will help keep some of the water entry back there. Neither job is tough and your bilge should stay dry after you do the work.

Nothing wrong with the shaft seals but the above methods are far less costly and should be effective. I would say I drain a couple of ounces of water when I put the boat back up on the lift after skiing for an hour or so.....and that works for me.

Yeah that's good, it's definetly not dumping in and it's normal I just saw these in the skidim catalog and like the trouble free no drip alternative to stuffing. Thanks all :D

The lips seals are carbon/graphite, not a standard rubber seal. You will not see the signs of graphite as you would with the other seal. We also suggest the water supply be used.

Thanks EJ and everyone else too :D I think I'm going with this.

I have had the PSS for about 7 years now. Works like a champ. Love it. Glad that it's 1 less thing to worry about. I've heard good things from the OJ as well. It wasn't around when I bought my PSS.

Be sure that you do NOT tighten your packing nut down so far that it never drips. It's supposed to drip somewhere around once every 30 seconds while "in gear". This is to cool and lubricate the shaft in the packing box. If you tighten so that it never drips, you will damage your shaft.

Check your owners manual for the exact amount of drips/minute.

Thanks jimmer, I'm in check with all that and my manual says 10-15 drops per min. I want zero and one less thing to worry about :D

I'm with you there Coz. After having a dripless, I won't own another boat without one. I'm not particularly bias between OJ & PSS. For me, either one would be on my boat.
