What you think as a problem is actually the normal function of a stuffing box. If it leaks
a drop a minute (it will be a bit more when the shaft is spinning), it is, in fact, operating properly.
I have a fibreglass boat with a traditional stuffing box with a Teflon-impregnated packing. The spiral of stuffing is three turns with the ends trimmed at an angle to more or less meet to make a "triple coil".
I inspect it once a year and have had to adjust it once in five years. I use surplus dental tools to put it in place, a job more calmly done out of the water
, by the way. The coil of packing I bought for 10 bucks years ago should last me until I die at this rate.
I also have a steel
boat with a PSS device. This is the so-called "dripless" bellows-type. Water
, if you're doing it right, never enters the boat. It's expensive and more finicky than a stuffing box, and it's generally an "all or nothing" proposition in that if it's working, you forget about it, but if it fails...whoosh glug blub!
But with steel
I don't even want an unnoticed drop inside. Your needs may vary.
