Until I can pull the boat, any ideas how to reduce the amount of water leaking from the seal? This seal has two o-rings.

Where is the leak evidencing itself? The blue tube aft of the shaft seal? The black seal where the shaft enters the seal assembly? Or???

Who makes the seal?

How much water are you seeing? At rest? With the prop engaged with the engine? While sailing?

The leak os coming from the front seal. When in the slip I am able to reduce the leak to a drip by using suffing material, hose clamp and plumbers puddy. A pretty solid stream when shaft is turning. Have not looked while sailing but my guess would be the leak would be reduced. Not sure who the mfg is. No name on the coupling and it's OEM from 1980. Changed out the O rings a gew yeats back. Had a minor leak when I put it back in. Leak was manageable up until about a month ago.

I've been in this business for over 5 decades and have never seen a shaft seal like that.
It makes no sense to have o-rings with packing. Can you draw where the 0-rings and the packing go?
Is there packing (Teflon or flax?) inside the brass/bronze fitting? If so, it looks all the way tightened, so all it might require is repacking.

Looks like a mechanical seal probably has scored/scratched faces. Does the bronze part rotate?
