What type of analog tachometer for Kohler V twin

[FlashandFlare 0]

I am looking for a electric signal/analog needle 0-4000rpm tachometer, but have no idea what to look for spec or what kind works on my engine. My tractor is a 93-94 Sovereign Hydro 18 with a Kohler 18hp Command.

A company called tinytach makes small digital tachs. I installed one on my four stroke outboard a couple of years ago. It's not precision but works well for my needs. They also can be purchased to include an hour meter. Very simple installation.
