[C320-list] Black Carbon Smoot

[Joe Barrett]

No water that I noticed, just black soot EVERYWHERE! I'll start with Paul's
recommendation of the hose leading to the Muffler and go from there. Can't
imagine a pin hole in the elbow could create that much soot. Any idea's how
to clean the engine compartment once I find the source of he leak?

Joe,

I would definitely start at the exhaust elbow. Was there any water (black)
around the aft end of the engine or on the engine cover?

I have fixed my engine starting problem. Turns out all the switches inside
the Navpod were corroded and needed to be replaced including the Bus Bar
terminal. Water intrusion was the cause.

Never ends though as I was motoring out for a Sail Sunday and a passenger
went below and said is there supposed to be black smoke coming from the
engine? I shut the engine off, went below and the entire engine compartment
was filled with black carbon smoot. I have no idea where it came from or
where to look for a cause. The engine is the 3GM30F Yanmar and my boat is a
2000 model bought new in September 2001. A crewmember started the engine
while I looked from the Aft cabin and it appeared to be coming off the top
of the engine.
Any thoughts? I usually run a bit higher RPM's than some on this list not
hesitating to run at 3200 RPM for long periods so I never thought about
buildup due to running long periods at low RPM's.
Please HELP!
