Had to go check pricing. It seems a toilet ring is about $6, where a 14oz tub of StayAfloat is about $16 (they make different sizes). It would seem quite worth it to just buy a tub, rather than try to create one.

Regarding the melting I am actually more worried about the other way around. I'd be worried that if stored somewhere cold, it would be too hard and brittle to work with when needed.
Interesting point. Although, I'm hoping I'm never aboard when it's so cold as to freeze wax.

I actually looked it up and found this at Jamestown Distributors.....

Stay Afloat Emergency Leak Sealant

Does cold or heat affect it?

Cold does not affect it. The putty will become harder but sealing properties are unaffected by cold temperatures. Heat will affect it and it should not be used on hot surfaces or engines with a surface temp over 120 F / 49 C. It is intended to be used in contact with water, ocean, lakes, rivers, streams

Re: Dripless shaft seal

The fiberglass tape is strong enough to repair an axe handle and will bond to pipes and hoses. Wouldn't expect it to stop a pressure leak but it sure could help to control it.

Re: Dripless shaft seal

Recent incident ..... An outboard was locked down and hit a bar. Broke the transome all around. Leaking badly they got to the lift but we're sinking quickly. My friend used toilet bowl wax to temporarially seal the transome leaks enough to keep it afloat until the lift operator got there.

I personally accidentally drilled a small hole in my hull. Not easy to do up in a steel hull!!!!! Real brain surgeon here. But a dab of the wax sealed the hole and she sat dry for a few hours before being lifted.

I have a couple of rings and a Chinese take out plastic tub of the stuff. Just melted it and poured it in. Maybe keep a ring next to each thru hull?

But.....we removed the drip less seal and went back to a traditional packing with some of that hi tech material. Runs cool and drips very, very little to not at all. Our seal is pretty accessible. For us going back to traditional was a great decision.

Re: Dripless shaft seal

I can think of 3 failure modes, one of which happened to me:

1. The ring moves forward, so bellows is not compressed adequately. I've had this happen on a sailboat and I have a friend who had it happen on a power boat.... and reported it here before, put something around the shaft in front of ring as belt and suspenders. Otherwise, figure on crawling into the bilge and somehow levering the bellows back, and somehow tightening the grub screws. Screws are single use. Lot's of other threads on this one.

2. Shaft disconnects from motor. An extra retaining ring can help here. If the shaft doesn't exit the boat, things are better. No power, but no big hole.

3. Bellows fails. I haven't witnessed this one, hope not to...but toilet wax or marine packaged equivalent or duct tape I guess as others suggested.

Or next to your electric drill. Heheh

I have a sauna on my boat, therefore I win.

Re: Dripless shaft seal

we had one fail between Panama and Cartagena while exploring some out islands. We knew we had to use the engine to get into Cartagena so as an emergency we used emergency tape to stop it then took it off when we had to motor. Jeanneau has a great system where the water goes straight to the bilge via a pipe. So the bilge ran a lot.
then when we got in and settled into the dock we taped it with emergency tape and tried to find a new one in Cartagena. Had to get it from the USA and took a bit of time. It had lasted 8 years.

Then after an Atlantic crossing the new one started leaking after 3/4 years. Got a new one in Tunisia (knew a man who knew a man - don't ask) and had a really good guy put it in without a haul out. Unless you really know what you are doing would not recommend it.

Now we carry a spare.

Just our thoughts and opinion

Personal sore spot. Happened to me;I think as the engine moved in reverse/forward shifting while fighting the wind in a tricky slip. If I had not been thorough checking the boat before I left her, I would have had a stick at the slip where the boat used to be. Amazing how much water comes in - I was nearly filled to the cabin sole in about 5 minutes, and have a 12"-18" deep bilge...

All PSS seals should have a collar fitted on the shaft to make sure the ring does not move. Two small grub screws (which cannot be retightened) is IMHO a major failure risk.

Or, get a toilet ring and divide it into 6-8 parts. Put in little tubs and give to your dock neighbors for holiday gifts... just tell them it is the thought that counts.

Re: Dripless shaft seal

Cousins, on a remote, rough logging road, 60 miles from the nearest gas station, had a leak in their gas tank. One ,just as a joke, said "Stuff bubble gum in it. "After laughing, they realized that they had no other option. Over an extremely rough, rocky road ,it lasted the 60 miles.
