The rpm gauge in my boat reads 1200rpm when the key is in the off position and the motor is not running. But when i turn the key on it goes to 0. My ? is will it still give me a accurate rpm reading when the boat is under power ?
Thanks

typically you should have an idle reading of 600-800rpm... if that is the case you are probably good to go

later

Mine does this sometimes. I think what happens is you shut the key of while coasting to a stop when the engine RPM's were still up. If I turn the key back ot it reads 0.

Your good as long as it shows 0 when the key is turned on
