Review on ELING Multi Functional Speedometer Tachometer Voltmeter Interior Accessories for Gauges by Tre Boyer

Revainrating 3 out of 5

An electronic matching circuit is required to be applied directly to the coil control signal.

I use it on my boat with a Mercruiser 3.0 liter TKS engine (it's a very popular 4 cylinder 4 stroke engine). Corresponds to the description, except for the overly sensitive speedometer input. I had to make an electronic adjustment circuit (see attached photo) otherwise I would have to send the device back because. With the engine running, it read 9999 rpm.

Pros
  • Operating voltage 12V DC, 1 year warranty, 100% waterproof and fogproof
Cons
  • Zero
