Default Leaking Shaft log

Has anyone encountered a .leaking inboard shaft log? I think I have a leak somewhere where the shaft log bolts to the hull.I assume the fix is to remove the prop shaft and remove the shaft log and rebed?Any ideas or experience with this would be appreciated.

Sounds like you are right. You have a separate shaft log bolted to the hull?

Don't have a picture at this time,boat is a old 36 Jersey sport fish ,I am guessing the shaft log was supplied by buck algonguin..I can't see all of it due to a bulkhead; it is bolted to the hull and sealed with some sort of black rubber gasket and sealing white sealing compound.

Ugh. Sounds like a pia to access
Better be darn sure that's the leak before you tear into this repair.
Things you need to check while in the water
Be sure water not pooling there from another source and not the packing gland just dripping down to the base
Get the area bone dry and surround with dry towels and see where the water shows

you need to be sure your shaft is straight. Look at the coupling and packing gland while underway. Idle speed and at cruise. Should run true w/o shaking. You should also put a dial caliper on the shaft and coupling and turn them by hand

Thanks for the ideas,there is a very slim chance it could be a fresh water system was down leak.Fresh water system was down hose goes thru a bulkhead very near this area.Fingers crossed hoping for simple fix.Will find out in next few days.

My boat is in saltwater so a quik taste helps me chase a leak. You could have bad clamps where the packing hose connects to hull or just loose. Could be a lot of things, keep us informed of your progress.
