I just bought a used boat with a 1983 50hp Mercury Outboard. While looking over the boat I noticed that the console doesn't have a tachometer or any other gauges.

I don't need a speedometer since my fish finder has GPS and shows speed and my fuel is in cans and not an internal tank, so no need for a fuel gauge.

However, a tachometer would be a really nice thing to have since it directly relates to how my engine is performing.

What I would like is a nice looking tachometer that has a dial/digital readout with a resettable MAX RPM feature so I can check on how fast my boat revs under various loads. That way I can change props if necessary depending on what I'm doing that day.

The dial would be nice, but I could use an all digital if that's what it takes to get the MAX RPM feature.

Any suggestions?
