To answer Bill's question, a gauge chance would be needed. A gauge with an adjustable set point set to 205 (or any point you want) which triggers an output that drives ?a lamp, buzzer, flashing LED. Datcon , Murphy, Stewart Warner for example offer these items. You would have to change the sender so it matches the gauge.
As for the fan, an air switch (sometimes called a sail switch) which would trigger the shutdown. Not hard to accomplish.
My point about the fan failure is not that the engine wouldn't shut down rather the temps approach 220 for Yanmar shutdown swtches and it's awfully close to scoring pistons. Scored pistons are the most common Yanmar failures.
