Dripless recommendations?

I have been working on our 1977 Willard and just pulled the engine to replace a leaking v-drive seal, cleaned the bilge like it has never been done since new, and am thinking I will replace the old stuffing box*and flax wrapping with a new dripless one.* Any thoughts on which brand to use or avoid?* Since this is in a VERY inaccessible place, I'm hoping to not "have" to see it much in*the future, so I'd love to hear what everyone else has experienced.

Keith, I think you hit the wrong forum button.

RE: Dripless recommendations?

I would not install a dripless system where you cannot regularly see and service it. Same goes for gore or flax but at least if they drip a lot you can tighten them. Once a dripless*system starts leaking you need to get right on it.* I*have two that are very reliable, don't drip and can be easily seen and accessed. I routinely look at them when cruising.

RE: Dripless recommendations?

I have had Tides driplesss seals, they use a lip seal, on 2 boats, on my previous boat a 2002 Camano in 2006 or 2007 the seal developed a slow leak, maybe 10 drops per minute. I was keeping that boat on a hoist so was able to change it out and installed a spare seal on the shaft.
My 2003 Monk has the Tides Sureseal it hasn't had a problem leaking but I did check the cooling water flow recently and found it blocked at the fitting which taps into the transmission heat exchanger. The fitting was completely blocked, mineral deposits, and no water was going to the seal the seal is not dripping and seems to be fine fine so I guess I caught it in time.
The owners instructions say to check the water flow every 6 months, I confess I had not checked it in the 3 years I have owned the boat. I will be buying a replacement seal and a spare to put on the shaft next time I haul the boat since I don't know what effect running without the cooling water may have had on the seal in there now.
Overall I am satified with the Tides seals and would have no problems buying another boat equipped with them. The bilges of the boats I have owned with them stay completely dry which is very nice.
On both boats the seal was visible on opening one of the salon floor hatches.

I also*installed a tides seal on my Albin and I installed one on my previous Mainship. Mainship was on 5 years never leaked a drop, never clogged a feed hose.

6 seasons on the Albin. Same results.

RE: Dripless recommendations?

If you follow the desires for maint on the "dripless" seals from their mfg , you will notice they REQUIRE maint.

I love the goretex replacement for flax.

No drips , no maint , and no heat on the stuffing box., waisted energy.

Sorry for posting this in the wrong category.*

Thanks to all for the informative posts.* We are installing a PYI PSS Dripless on our Willard 30.* This weekend we got to clean the engine bilge compartment and found a cell phone, screwdriver, various assorted bolts and nuts, zip ties and gunk.* Now it is actually clean enough to recognize the bottom as fiberglass.* Very nice!*

RE: Dripless recommendations?

The Eagle has a PYI PSS Dripless.* Installed in 1996 as I wanted the bilge bone dry and the PYI PSS Dripless*the only option at that time.* Also if the shaft was bent the PYI PSS Dripless could still hold a water tight seal and the bellows flex.*
*
We have the dripless bellows check every time the Eagle is pulled.* The bellows should last 10+ years just like hoses, belts, and the boot for in/out board drives.* 15 years we have had not problems/leaks and have changed the bellows out once.*
*
The extra precaution I have taken is to run a caulking seal around the SS shaft collar just in case the rubber 0 rings fail, and there are two 2500 bilge pumps.* If the bellows does leak, I would wrap in Saran wrap to slow/stop the leak.**

Dripless recommendations?

Keith we installed the PYI system on Beach House and now have 2800 miles on it. I have installed probably a hundred or so of these on other boats over the years and all are still in service today and the owners love them. Good luck and hope all goes well with the reinstall. Chuck

Claude, The Tides seal, especially the older units were notorious for leaking. I think you will be very happy with the PYI. Chuck

*Really? Actually the reason I went with Tides both times was because of the opposite.

RE: Dripless recommendations?

Make sure the bellows put a lot of pressure against the collar to make a good seal.* As an addition precaution I caulk round the color and the shaft*incase*the O rings failed. Also a hose clamp around the shaft as an addition precaution to prevent the color from slipping taking the pressure off the collar. Also when you splash make sure you burp the bellows to get the air out.

*Actually, too much pressure is a bad thing. The manufacturer will recommend how much compression is needed. I would not recommend using any caulking, we have never had an O ring fail in over 15 years. The hose clamp is a good idea or a donut zinc, as we used for safety.

Good luck Claude, and when you order, have them send you spare set screws in case you need to move the shaft for maintenance or repairs later. The set screws should not be reused. Chuck

I'm with FF on this one. Replaced the stuffing with Gore when I did the cutlas bearings five years and 500 hours ago. No problems to report.

RE: Dripless recommendations?

The big advantage to the modern material in the stuffing box is the style of failure.

Should the packing wear , it will drip a bit.

Should the bellows rupture the inflow is beyond most electrical pumps to clear.

Big difference!
