Tachometer for Diesels

RE: [S2Yachts] 9,2A TACHOMETER

There's a cheap digital tachometer you can get called Tiny Tach I think.
There's a little transducer that fits around the fuel injector pipe and a
digital readout. It costs about $70. When I had the boat surveyed she
maxed out at 3117 RPMs under load, the Tiny Tach showed 3114 at max.
Accurate enough, and best option i found available for the money.
