I do have a groco filter. The blockage was
on the onboard side of the thru hull main water intake, the chips never made it
to the filter. They got mashed on the inboard side of the valve. I dug them out
by removing the hose and digging out the top side of the valve. Again there was
water flow, it wasn’t totally blocked, but when removed I had a geyser as
I should.

Yanmar Question
One thing you should consider
installing is a raw water filter. I have a Groco,installed just above the
waterline,and it catches all the detritus except the dreaded plastic bags.
Also,make sure your water intake lines are non-collapsible

Ok, from the two replies
so far sounds like you both suggest the black substance in the cooling water
could be fuel/exhaust from a blown head gasket, cracked head, or cracked block.
The overheat I experienced was very minor. I knew there were a lot of wood
chips in the water, lots of engines on other boats were getting clogged and
overheating. This happens every spring in our lake. I watched my temp guage
regularly knowing I could ingest some chips. When it over heated I caught it
right away and it only got up from normal operating temp of about 160 to 180,
it would only go to 180 when I ran over 2500 RPM’s. As soon as I hit 180
I would idle down and it would cool right down. It was only at 180 for a few
minutes. I understand I don’t do damage till I get to over about 200 degrees.
I can’t imagine I did any serious harm with this incident. I cleaned out
the chips when I did the fuel pump and secondary fuel filter with the mechanic
and it cooled right down and no longer overheated. The line was only partially
blocked. Can I run the engine and use the boat before I get the mechanic out
there again? It is a big deal to get him out there. The lake is remote.

Yanmar Question
Possible blown head gasket, cracked head, or block.
Fuel/exaust gases can enter your cooling system any of these ways. Have your
mech do a “leak-down” test. this is more accurate that a quick
compression check especially when dealing with a small crack/break.
I say again, this is a possibility only.

Fellow
Owners:
I am no diesel mechanic, but I am learning as I
have my engine
serviced by a mechanic. Just had the primary fuel
pump and secondary
fuel filters replaced on my Yanmar 2GM to
hopefully rid of the last of
my minor fuel leaks. However, a mystery appeared.
We were changing the
fresh water coolant and noticed a back oily
substance in the system.
Couldn’t tell if it was fuel, or oil, the mechanic
changed the fluid
filling twice with antifreeze and the back stuff
is mostly gone, but
sure wonder what it was. Does the fresh water
system come in contact
with the fuel system or block where oil would be
present? How might
oil or fuel get into this system? The engine had
been overheating just
recently which we traced to fine wood chips
clogging the main seacock
for water intake to the engine, when this was
cleared, the overheat
went away. Any ideas on this oily substance in the
fresh water cooling
system?
