Hi Neo,

Welcome to the forum. Which electrical plan are you after? The one of the boat or the Mercruiser diagram?

Did you have no manuals that came with the boat?

Hi there,

The 12v electrical diagrams for a 2006 Bayliner 285 can be found at the end of the supplementary manual for that model, available on Bayliner's support site here.

Some diagrams for a Mercruiser 350 Magnum can be found here (see further down) and here (harness).

What appears to be the problem?

Thank you for your help. I will watch and see.
The problem with the tachometer. With the engine's all right, works like a clock (excellent).
Tachometer needle shows momentum, more than it actually is. The problem is not with the engine.
Therefore, ask for help with finding electrical plan. To see the connection diagram tachometer.

Tacho's aren't very reliable at the best of times.

Is there any chance somebody has changed the setting on the back of it?? I'm guessing it's the standard faria one, if so you can alter the spec for different types of engines. If this was set wrong, could cause odd readings.
