QI have replaced my stengland packing as per instructions (three rings) but it still leaks water, and grease comes out when I turn the greaser.
website TONY REPLIES... Grease issuing from the gland often indicates loose adjustment or defective packing rings.
Some glands use more than three rings. Keep adding rings until the last one, when pushed home, is just below the end of whatever it is pushed into, so you can get the pusher/hollow nut back in place. Tighten each nut in turn by an equal amount – say one flat (1/ 6th turn) – until you can feel the packing starting to grip the shaft when you turn it by hand, then tighten the locknuts. Run the boat in gear: the gland may run warm, but if it runs hot, slacken the adjusting nuts slightly.
The gland should leak water at one to two drips a minute, which stop when you use the greaser. If you
Acannot stop the leaks by adjustment, you will have to look further. Assuming you were accurate when you cut the packing, these symptoms could be a worn shaft, broken engine mounts, a misaligned engine or a bent shaft. Remove the packing and use a piece of bent wire to feel the surface of the shaft to assess any wear.
Ensure there is enough packing
Then tighten the gland nuts
