Yanmar 1GM10
Do you mean the hole where the shaft that drives the impeller goes
into the engine or a small hole on top of the pump housing?

Good morning
I hope someone can help with an annoying problem.
I have a Yanmar 1GM10 inboard on my small sailing boat. It runs
really well. Recently I had it serviced, oil changed etc. including
replacing the impeller.
It has had a salt water leak for many years before I owned the boat.
I have only owned the vessel for 2 years.
The salt water is coming through the impeller housing, and dripping
from the designed hole between the impeller and the engine. I sense
this is where the engine shaft goes through to drive the impeller.
It is not coming from a gasket - that would be too easy! I did not
see what the seal is like where the shaft enters the area of the
impeller. Is there a replaceable seal there? Will it need a new
impeller housing? I hope not. No gaskets are leaking at all. He
put on a new gasket when he replaced the impeller.
I would appreciate any information you may have in this regard.
Many thanks
