Sterntube and shaft design help for new build 10m boat

Thanks for the fast reply.

I was looking for a supplier of GFO here in the EU without success. If anyone knows an online store selling this please let me know.

My boats make about 700 hours per year that is why i ask. Just now i came of one boat that has a terrible leak at the gland. It's anoying...

I use rigid packing gland attached straight to the stern tube. This is transmitting more vibration but is bullet proof in the winter when freezing water in the tube can push the rubber hose off the stern tube... Ask me how i know...

This spring i almost lost a boat with a Volvo rubber gland.... It was filled wit water on the point to sink when i got a phone calll...

The new one i am building has to be better... I hope

Daniel

 

GFO is good stuff, maybe order in the USA and have it shipped.
Definitely worth the trouble.

Contact Gore who makes the packing, they have worldwide distribution I think.

Must be a way to buy this in Europe. Video is good to watch.
This packing is soft silky smooth square rope. Likely there GFO marine packing is the same as the pump shaft packing.

Yes SamSam,

It will be noted in the "log"

When i have removed the old tube i had to cut it out as it was embeded in the epoxy.

That log kept the hull afloat when the Danube flooded this spring and it was dripless )

Cheers,

Daniel
