Day before yesterday I took the boat out for a short cruise. My stated purpose was to make sure the fuel stabilizer I added got mixed in with the gas. :grin:
Anyway, I was on plane, set RPM at about 3500, and noticed I was doing less than 25 MPH. Chartplotter confirmed the slow speed. The tach was steady, like it really believed that RPM. Remembering from the old board the problems with the switch on the back of the tach, I stopped the boat and pulled the instrument panel. Then wiped the # cylinders selector switch back and forth a few times.
Buttoned it back up and tried again. Sure enough, just wiping that switch back and forth a few times added at least 5 MPH to my speed! :smt038
