Hi there,
I have Yamaha 40HP 2 stroke outboard and have two questions about it:
first how to determine what year of production is engine?
It says on stamp...40 HEO

second, my temp gauge doesn't work...it's brand new unit and I think I connected wires properly but it doesn't move the temp needle
any ideas or pics what to connect?

thanks
 
The complete engine ID is needed. It will begin with the number 6. One the side of the motor, on the decal, right below the model identity.

A temperature gauge needs 12 volt positive, a ground, and a reference signal from a sender. The sender itself also needs to be grounded. What type of gauge is it? Does the needle move at all when the key switch is turned on or off?
