Leaking coupling

The blue and green sections of the prop shaft shown in these two photo's are leaking water. Any advice on how to repair this?

Thanks,

Check out this site for info on the gland in your foto.Re-Packing A Traditional Stuffing Box Photo Gallery by Compass Marine at pbase.com
Theres a lot of corrosion on the metal showing and it looks as if your engine supports are close to failure.
Safe sailing

Looks like that gland has been spraying water around for some time.. the shift cable bracket and nearby tank are looking pretty bad.

It also looks like there's not even enough space between the gland nut and the shaft coupling to do a proper job of repacking. Good luck with this, it's certainly something you should do (using help from the link in the above post) sooner rather than later.

And I would start spraying that engine coupling with PB Blaster or WD40 regularly so that you will be able to get it apart when the time comes.

Thank you for the link... I was unsure how the assembly worked. I went back in to look and found the locking nut had backed off and thus the packing nut was very loose. I hand tightened, i.e. no wrench just with my hand and the slow stream of water is now just a drip drip drip. I have a local boat mechanic coming by tomorrow to have a look.

It is not my intent to let it slide so thank you each for the replies.

You may consider replacing with a PSS Shaft Seal, but it may be tight. You would want to call them before with some measurements.

There's a lot of corrosion there? I wouldn't doubt if you have to cut the shaft to get the coupling off, which means a new shaft, coupling, and either new stuffing box or shaft seal.

Cheers,

When properly tightened you should just get a few drops per minute when runnning. The stuffing box should stay cool (the water lubricates the packing and cools it). You don't want it to stop dripping completely. Then snug up the locking nut to prevent it from backing off again.

The big issue right now is the damage done to the shift cable mount and more than likely the throttle as they both look ready to fail at the worst time like docking


I had the same disaster going on when i got my A4 as it also ate up the rear motor seal and was leaking a LOT of oil and not enough space to change the packing without taking stuff apart






You dont have to everthing i did BUT your gonna have to turn back the clock a good bit to make it safe again
