Stuffing Box Hose Question

(1/2) > >>

Chance:
Has anyone replace their stuffing-box hose ?  Chance has the  original hose at 41 years . It looks fine and feel okay but not sure if might be a problem underneath the hose .  Fresh water Lake Michigan 6 months in and 6 months on the hard.

Now is the time to purchase the PYI dripless stuffing box kit.

I installed one 20 years ago and it is great.

PYI recommends replacing the rubber bellows every three years. I didn't know that and had no problems for 12 years.

 I replaced the old one and kept as a spare since it is still perfect.

Be sure to file a slight chamfer on the end of your prop shaft so as not to nick the o-rings upon installation.

One other note- When I bought mine I chintzed-out and bought a model without a vent.
At that time there was a 'low RPM' version that did not need pressurized water cooling.

The only problem is dying sea life creates a bubble of gas that builds up when the boat sits.
If the bellows is not 'burped' it my get hot. I never suffered a failure but I did get the kit hotter than I like once.

Now I simply remember to burp the bellows when I check the engine before startup.

The modern version has a vent tube so this isn't an issue-

You will be very pleased with the PYI dripless kit. No water ever.

I second the vote for the dripless seal.  A little burping every now and then is all you need to do.

However, when you install it, make sure you add a collar behind the rotor - a good article about installing the PSS seal is here, and it refers to the collar:
http://www.pbase.com/mainecruising/pss_shaft_seal

The rotor itself is held onto the shaft with two small set-screws.  If these lose their grip - which happened to me - the rotor can slip, and water will come in. It will take 3-5 minutes to reach the cabin sole...a collar is cheap insurance, quick and easy to fit.  Most boatyards do this without being asked; as I discovered, not all...

Apart from that heart-stopping moment - which also reinforced the need to do a quick overall boat-check before leaving her - the PSS has kept my bilge dry for many years.

Alma:
Yes I like that website too. Lots of good information about a lot of things. An additional clamp can't hurt for sure. A zinc anode could do double duty as the safety collar. I've often thought of the rotor itself as a clamp to prevent the prop shaft from flailing around if the coupling comes loose. I never thought the rotor would need a backup. It surly can't hurt.
And an additional zinc (aluminum) anode backing up the rotor just might come in handy one day...
