I have a fault with the rpm gauge of my boat. When you power it up the needle goes all the way around to the maximum revs. The boat has 2 engines with 2 gauges and have tried swapping the gauges around etc to find out if it is the gauge or an earth fault etc. It is the gauge. I think it has been repaired before but what im after is someone who can repair it again. Does anyone know someone who can repair it? Thanks in advance.
