How do I check if my rev counter RPM is the same as Engine RPM ?

Cheers

Hi Muc
I have the scan tool but never used it,so the scan tool will actually tell me what the RPM is

Yes, the scan tool gives rpm.

Re: Rev Counter

With power off should the rev counter be at zero ???

Re: Rev Counter

Soome do & some don't. It makes no difference what it reads with the engine off -- you know the RPM is Zero. You are interested in it's accuracy with the engine running! Check it at 1000, 2000, 3000, 4000 and 4500 -- ON THE WATER OVER 2000 RPM, NOT IN NEUTRAL.
