Hello, I got my tach hooked up and working, thanks for the information. Now the problem is do I have the right tach or the right tach module? The tach reads up to 6000 RPM. When I ran my boat the other day the 68 500 I think with lightning ignition maxed out the tach well before full throttle. The tach module I have is numbered 332-4811A2, I saw one for sale the other day numbered 52552A3. What RPM's will this motor run at ? Is the tach too low, is the module incorrect ?
