Where would the tranny temp sensor go? On the output side of the tranny heat exchanger?

I think it is easier to just change the tranny cooler. The one for my yanmar is distributed in the USA for less

Than $200.

I'm not sure what you could do on the liquid side.  Once the transmission oil is sucked out by the seawater flowing through the (perforated) cooler, friction quickly builds up heat in the transmission but there won't be any liquid in the lines to the cooler.  You would have to put a sensor on or in the transmission case.

Replacing the cooler every 2,000 engine hours might do it (as suggested), limiting the time the cooler has to corrode.  Checking on the bonding wire occasionally would also be a good idea, I believe that was the problem with my boat.  The failure happened within the first 10 engine hours of my ownership.

I just wanted to note that sensors on the seawater lines were not going to protect the transmission.

Just a suggestion: 

It might be easier to monitor temperature of the transmission oil and the exhaust temperature using this:

I had installed the Borel alarm, but there was never any indication it worked and I never knew the actual temperature without going below with my laser temperature gun. But, of course, I never had an overheating situation.

Hi Bill,
How would you mount it on the transmission?

Kent,

I would attach the probes with appropriate size hose clamps.

Hey Kent,
Or bed them in a dollop of JB Weld left over from us installing your arch.
