On CottonBay we do that every 6/7 years and do 120-160 hrs /
Year, so I agree with 1000hrs,
We NEVER had water in the Cdrive, never....
Next I will put on the bronze speedyslives, so I expect to never
have to change anything ...

Amel recommend replacing the 3 c drive shaft seals and the
wearing bearing every 1000hrs. Most of us do the change
biannually regardless of hours. It is an easy and relatively low
cost preventative maintenance item done conveniently at a
programmed haul out. If yours are over 4 years I would place
that very high on the probability scale for water ingress. Both
the seals and the wearing bearing should be replaced. I wont
express an opinion on the sealing of the plug.

I would guess the
chance of having water inside the C-Drive 4 years beyond
service date is very high.
Regarding the drain
plug area, is the GRP also cracked? See below:
I am sure it must be an illusion, but the mark in the
metal appears to be raised. I am going to assume that it
is an indention. The shell of the C-Drive is made of GRP,
and there are metal inserts that support bearing
connection points, seal points, and this particular drain
plug hole. I think you need some expert advice from
someone knowledgeable of the manufacturing process of the
C-Drive in order to find the best solution. I will offer a
temporary recommendation, without any direct knowledge of
the C-Drive manufacturing process: Since there is not any
significant positive or negative pressure inside the
C-Drive, I would be tempted to use Silicone RTV to fill
the indentation of that scratch and also on the O
Ring...at least until someone can offer an expert

Here's a related problem- either a crack or deep
scratch along the surface that seats the V-plug O-ring (see
Last haul out my oil also came out milky, but the propshaft
seals were 4 years past changeout date, so I can't know
whether seawater got in under the O-ring via this crack or
through the mainshaft seals.
Anybody have an idea for a fix? Fill it with epoxy and
sand it fine? Somehow put in a new seating?
