I replaced my temp gauge just yesterday after having the same problem and
finding that replacing the sending unit did not solve the problem. It is
very easy. It will take longer to take the pod apart and get to the gauge
than it will take to replace it! New ones are available from Seaward,
562-699-7997. Cost was about $45. You need to give them your hull number
and they will take it from there. As the guy told me, they make a good
product but they are not marine grade. My boat is a 2001 vintage.

Subject: [C320-list] Temperature Gauge
The engine temperature gauge on my 1996 vintage Yanmar 3GM30F seems to have
gone haywire. When turning the key on the gauge needle pegs itself all
the way over to maximum hot even though the engine cooling system seems to
be working perfectly well (no blockages in the strainer, normal water flow
coming out of the exhaust, no apparent overheating of the engine). I ran
the engine for several hours on a cruise last weekend, and except for the
gauge, all was normal.
Thinking that there might be a wire connectivity problem (corrosion)
somewhere I spent some time the next day cleaning all the wire ends and
terminals in the gauge with sandpaper. Still no luck. So I'm thinking
that either
the gauge is broken and will need to be replaced, or perhaps the wires at
the engine side are either loose or corroded. The only problem is I don't
know where the wires on the engine side are located. Any suggestions would
be greatly appreciated.
