Re: Propeller Shaft Log

Thanks for posting this... I am looking at the same issue for my C30, not pouring right now, but dripping. No idea when the last time it was repacked.....

Re: Propeller Shaft Log

Having the same with mine right now. Bilge on every hour or two. Found the same symptoms under my floor. A lot of blue green corrosion on a nut and washer with a steady stream just a bit more than steady drip. Adjustable? or Worn the f out? Coming out of the water in the next 3 weeks for bottom paint and zincs... Do it your self? parts avail easy enough? Vancouver BC... Would like to have it all ready to go as I hate the boat sitting waiting for parts....when the weather is nice enough to work on her we end up going out sailing instead!

I'd say the yard was more than fair. Haul and launch around here for a Cat 30 would be $300 or so, $100 in parts. Sounds like they didn't charge much for labor. This is one job that's a real pain on a C30 - Caleb's right about the contortions. Access to work on the engine is great, acess to the stuffing box is a bear. Mine was also seized and it was impossible to get a wrench on it. Replacement makes a LOT of sense.

Sounds like you've got a good yard.

Re: Propeller Shaft Log

It sounds to me as though you got a pretty good deal although the materials probably only cost around $100. A new packing box, tube, hose clamps etc. is about $80: PACKING BOX ASSEMBLY BRZ 1" SHAFT 2" HOSE 103450
New packing material is around $20.

Re: Propeller Shaft Log

Update and I hope final statements to close this story:

The boat was pulled out of the water, and the stuffing box replaced with new hose, new hose clamps, and they made it longer to tighten down on a fresh part of the propeller shaft. Stating that the propeller shaft was a little warped and worn out where the last fastening was. New packing and packing nut. And, finally, a much dryer bilge. It was sort of an emergency for my piece of mind because I was heading out of town, and didn't want to think about that auto bilge pump fighting a leak for 5 days straight. At least I know it's new and been gone through, and I can clean up my bilge and start "fresh".

This time it was a $550 piece of mind. Most of that being the haul out and labor.

Thanks for your input everyone.

Re: Propeller Shaft Log

Stuffing boxes do not usually fail catastrophically but if you don't know when it was last re-done and it is warning you now (eg., not dripping but pouring) it is time to replace the packing. Packing is cheap, ~ $25.
Start spraying a penetrant like PB Blaster, or ATF on the nuts now and allow to it sit for a while, days even. The nuts will move eventually with the right tools and lubrication.

A very temporary fix would be to stem the leak from where the shaft exits the boat on the outside (underwater) using candle wax, Butly tape or whatever works.

Re: Propeller Shaft Log

They did not replace or do anything to the flax or stuffing box when it was out for the cutlass bearing.

a guy in the yard pushed on the propeller shaft and commented "might be loose" but that was it.

I took a look tonight and I'm almost certain its the 27 year old original nuts. All covered with greeb/blue crusty corrosion. Oh yeah, and pouring water. Like a faucet 20% on... Much more than drips..

There's 1 boat yard in my marina so ill walk over there at 730am when the open tomorrow. Get some insight and quotes. See if they want to haul ot out or do it in the water at their dock.

There's no way I could tighten or loosen the nuts. Lack of big enough tools but primarily its all stuck like a rock. The water is coming in the bottom behind the nut and onto the shaft. Between the nut and transmission is where its dripping down from.. Er, uh Leaking down from.

Hopefully some pros can fix it before I head out of town Wed afternoon and I don't have to worry anymore. Bilge pump is turning on once every 30 - 45 minutes for a couple seconds.

If the yard replaced the Cutless bearing, did they also re-pack the stuffing box at that time?

With new stuffing there is always a bit of a "break in" period where you may have to adjust the packing nuts a bit for the best setting, fewest drips.

If the packing was not replaced then keep tightening it a little at a time. I think that re-packing a stuffing box is a 10 year maintenance item (unless it fails first!).

Re: Propeller Shaft Log

Thanks everyone those are good suggestions. I'm going to tighten the nut a little tonight. Empty out the bilge and see how quickly it fills again by tomorrow. Then going away for a week so hopefully the auto bilge does its job.

Is it possible that from one-time to another of motoring, it will leak more or less? It seemed fine after one sail trip, then worse after another, then back to leaking less, now leaking more. I hope this is the only leak. The boat was hauled out a month ago for bottom paint and the cutlass bearing replaced, nothing else alarmed the fellows at the yard.

I would not tighten the packing more than once without the shaft running in between. Shafts often are no longer perfectly round and you could easily overtighten without realizing it.
