Greetings group,

Was making late day ski run yesterday around 8 pm and boat felt sluggish and then auto bilge went to work. Lifted cowl and peered at 4" of H2O in the flase bottom (and growing). Quick trip to ramp and checked for any discharge from engine and or exhaust system while waiting to trailer and every thing was dry as should be. This morning I removed cowl and center/back floor, filled bottom with hose and looked for tell-tell external drainage and found water exiting from area where prop shaft enters hull. Is this an indication that I need to repack the shaft or is there another seal that I should consider? Any advise or direction that may expidite a quick fix, if possible, would possiby allow a chance to get back on the lake today. If repacking is the answer is the only place to pick up new rope at an inboard shop? Would Overton's have it? I have read the instructions supplied by "east tx skier" and feel it's a doable FIY. Thanks for any help.

Loosen the jam nut on the packing seal housing then tighten the housing to compress the seal. Re-tighten the jam nut and go skiing... ( ;

www.skidim.com offers the packing rope and the newer goretex rope. It is an easy fix.

Sorry to threadjack, but I have an issue in the same area and can't find another thread that's close.

I have a 95 Maristar V225 and it leaks around the shaft. I can't keep the big brass nut tight. It has new packing rope and I get it as tight as I can, then tighten the jam nut and head out. After about a half day, the big nut has worked itself all the way off the threads.

Any thoughts or suggestions would be greatly appreciated. Thankfully, my bilge works, but I don't like everything (floor boards, carpet, bilge) wet all the time.

Did you stagger the joints in the packing material?

It sounds like your jam nut is missing. See here (http://www.pbase.com/mainecruising/stuffing_box).

There are two nuts and usually holes in the nuts for lacing wire. The lacing wire would prevent the nuts from loosening.

I am considering changing mine which I am sure is original and has most likely been leaking. How difficult are these to change?
