I have a 2001 Hunter with a Yanmar 3gm30f. I had a PYI PSS seal installed 3 years ago and do a visual inspection at every use. I have noticed a small amount (1/4 cup or so) of water collected under the seal occasionally and am wondering if the yard put enough compression under the bellows. I am probably 2-3 years away from a bellows replacement but am contemplating re-compressing the bellows. I know from the excellent advice on this board to use new set screws. Now for the questions:
In loosening the rotor, how best to lubricate the O-rings to slide it back to the neutral point, and then re-compress? Should I squirt liquid soap into the gap between the rotor and shaft on the coupling side? I guess I am worried that salt water on the bellows side may be putting a 'set' on the bellows side of the O-rings and if I try to move the rotor it might roll or otherwise distort the O-rings. Should I 'twist' the rotor axially while trying to move it longitudinally?
The shaft is fairly clean and bright between the rotor and coupling
As always, your most excellent advice is appreciated.
