Hi oh Great Source of collective wisdom, I need to change out the engine
mounts on my Yanmar
, 3QM30, in my Endurance 35 Cutter
There is a flexible coupling plate that joins the Stainless shaft to the back of the transmission
, with four large studs fore and aft, that I will need to remove in order to disconnect the engine
from the shaft so I can lift
up the engine a bit.
I am assuming that the next step will be to slide (pound/drive
) the shaft back a bit so that I can free the engine from the shaft.
The Stuffing box looks old and green, but seems to be working well. The manual for the engine (1980 model) observes that the stuffing box has lignum vitae in it. It is connected to the stern tube with a short length of heavy hose and hose clamps. A small water
line from the heat exchanger
pump">raw water pump connects to this short length of heavy hose.
My question is, should I loosen the nut (a lot or a little)
before I try to slide the shaft aft? Will it leak a lot or a little? (not a big issues as I have a big bilge).
I am planning to polish up the shaft a bit in front of the stuffing box, before I try and slide it, with some emery cloth.
When I get out to the boat
this morning I will try to get a couple of pictures.
