[C320-list] Yanmar trouble

[Rick Sulewski]

Check fuel filter to see if there is any substantial amount of water/debris
at the bottom of the filter bowl. May be picking up the debris & water at
the bottom of the tank. If you have a substantial about of water in the
bottom of the spin-on fuel filter, you may also want to check the on-engine
fuel filter if there is one on your engine.  Some amount of water can
collect over the years at the bottom of your fuel tank given the age of your
vessel and the potential for water to merely enter at the fuel cap due to a
loose fitting rubber washer, in addition to condensation if you run a low
amount of fuel in your tank.

I'd strongly suspect fuel filters are clogged.

No wind in Cape Cod bay so we have to motor all day. The fuel Gauge reads 
just over 1/4 tank and suddenly the rpm's drop. They go up and down a bit 
until the engine finally stalls out. After a few minutes wait, I restart her

and she runs for a few minutes at lower rpm's then dies again.

Any thoughts for trouble shooting? Tow Boat US is going to be expensive!
