After a bank holiday weekend of sailing and getting to know my new boat I was motoring back to the mooring, and waiting for Poole bridge to open, when I noticed a pool of water on the cabin sole. Closer inspection showed that the bilge below the engine was full to the cabin sole with water. The boat is a longer keeler and the bilge therefore quite deep, so as you can imagine this was a bit of a shock. I later found that the stern gland had become detached from the hosing that connects between it and the stern tube and keeps the sea out.
We managed to pump the water out and keep on top of what turned out to be only a steady trickle, while we motored back and secured the boat to her mooring. I found the stern gland had come loose, pushed it back onto the rubber hose and tightened the jubilee clip. Panick over.
I'd be interested to know if anyone else has had or heard of a smilar problem and can offer advice.
The gland is a PPS type with 3 rubber seals and is lubricated from an oil reservoir in the cockpit locker. It slides over the prop. shaft and is postioned about 4 inches from the stern tube, through which the shaft passes and out into the sea. A length of rubber hosing is connected between the stern gland and the stern tube. It is pushed over the ends of each and held in place by two jubilee clips at the stern tube, but only one at the stern gland. The gland end isn't long enough to accomodate two clips. I've tried fitting two, but the second just slides off as I tighten it.
The stern gland is smooth where the hose is pushed on. I've seen some models that have a raised ridge over which the rubber hose is pushed helping to keep it clamped in place.
I bought the boat last year and it was launched in April this year. As part of the refit I replaced the rubber hose. The new one was bought from a reputable marine engineer after I described what I needed. He replaced the stern gland oil seals at the same time. The boat has approximately 10 engine hours since launch. It's a 29ft sailing boat with 10HP diesel engine.
Do these types of stern gland installation need regular checks to ensure the jubilee clips are still tight and that the rubber hose isn't working its way off the gland, or is my problem unusual? Bearing in mind I've had 10 hours on the engine since I refitted the installation, this would suggest that checks should be made at slight less than every 10 hours, does this sound normal or excessive?
Is it advisable to use some sort of adhesive to ensure the hose is held firmly to the gland, or should jubilee clips surfice?
Any oberservations or advice is greatly appreciated.
Thanks in advance.
