Rpm gauge issue : I got my 270 in the water this past week. She ran good. When I bought it I noticed the rpm gauge was stuck at about 800rpm, I replaced all all the gauges and updated the drivers helm area, after the gauge was good till I took fired her back up the rpm gauge went back to stopping at 800 or so , it reads while the engines running fine . Any ideas?

So the tach was NOT one of the gauges you replaced?

On the back of the gauge is a switch that lets you select how many cylinders the engine has. Slide that switch back and forth a few times. Might clear up your problem.

Yeah I replaced all of them, I know the switch you are speaking of, thank you
