In the long term we will have to fix up this drive train so it can be more maintainable, a dripless gland or shorter coupling to get more room for repacking.
The coupling was not quite what we had ordered from the supplier, it should have been shorter, the grub screw you see on the brass coupling does not hold the coupling on to the shaft instead it locks in on the nut that holds the coupling on to the tapered end of the shaft. But, all that is a long story and we are stuck with it for the time being.
Once the water clears in the bay (weeks of rain) then we can dive under the boat and have a crack at the problem from both sides. Until then the electrical system
is being done & there is a great birds nest of wires around the interior
Thanks for the tips and tricks, we will keep advising of the progress.
