Hardline Products HR-8061-2 Hour Meter/Tachometer for up to 2-Cylinder Engines

Have had two of these for several years now and the important thing is that they are reliable, Don't buy the cheap chinese copies as they are flat out lasting a few months.

I recently installed a new engine in a piece of railroad equipment. Previously tracking maintenance intervals was sporadic. This little unit is simple to install, it has a 10 year internal battery, so no difficult wiring interface with the ignition system and vehicle power. The trigger signal comes from a pickup wire wrapped around an ignition wire. The Onan engine in my railcar is “lost spark” technology like a Harley. This unit can be adjusted for many different ignition schemes. Very easy to install, just wrap the trigger wire around a spark plug wire.

Product is shipped in reasonable time. Works as advertised. Convenient and cheaper than importing it yourself.

Nicely packaged and works great. Seems to be well built for the size. The only down point was that there should have been some double sided tape in the packaging but it was missing. No real issue as I had some at home. As a product and quality, for me it's a five star.

Installed this on my new outboard motor it’s simple and of high quality and pretty accurate a must have item to break in the motor shows rpm and total hours
