Summary: 


This sounds like a very good Idea. I have never seen the "horn" on a motor
but Mercury motors (don't know if all models) have a thermal switch that is
mounted on the block that cuts off the ignition when it overheats. (A
horn CAN be ignored...)

I personally fried a 75 horse motor due to lack of water cooling. A water 
deflector plate was missing on the lower unit. I started the motor and
checked that water was flowing, it was... great I says... I roared off into
the never never only to discover that at high speed the deflector is needed
to properly fdeflect water into the cooling system. When I slowed, water then
returned to the system and turned to steam as it hit the cylinders...
They didn't crack, but they was fried... A guage would have helped.

I can also say that the owner before us told us that he personally had
fried a pump impeller by running it dry. Rubber is just rubber...
