1975 merc. 650 65hp. I would like to install a temp gauge. It is on a pontoon boat and i have to raise the sun deck to see the pee stream. There is a plug near the top of the rear cover on the motor, looks like an 1/8th inch pipe plug. Could i install a sender unit here and run to a dash gauge? Any advice greatly appreaciated. Thanks, Allen
