Experience with Dripless Shaft Seals
I had the Lastdrop on my 39'' sailboat and it almost sank me! Fortunately I had carried the old stuffing box and was able to change it out while tied to a mooring ball at Catalina Island. After reviewing PYI’s at a boat show, it appeared better constructed than the Lastdrop I tossed over the side. With PYI’s, the shaft can move in and out a bit while maintaining a seal because of the bellows; the Lastdrop was less tolerant and plastic. Needless to say, I’ll keep the old stuffing box with the Teflon packing, it’s forgivable and for shaft alignments or whatever that might lead to disconnecting the shaft from the transmission, I can do it in water and push the shaft back without worry of breaking the water seal.
