## Description

Hardline Products HR-8061-2 Hour Meter/Tachometer for up to 2-Cylinder Engines : desertcart.ae: Automotive

Review: 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.
Review: Great product! I installed this on my Suzuki DF 2.5 single cylinder, 4 cycle outboard motor so I could monitor the rpms and hours for the engine break-in protocol and later to track hours for routine maintenance intervals. I had done a lot of research and found that there are some other products out there that are difficult to install and/or inaccurate, but this Hardline product was a very simple and secure installation and is accurate. There was no adjustment required at all- I installed it and it worked. Now I can run my engine by rpm rather than guessing by half-throttle, quarter-throttle etc. and don't have to guess how many hours are on the engine for maintenance. And, the price is right. Highly recommend. In addition, Hardline advised when I asked that you can use regular 18 gauge wire of 10, 15 ft if you need to place the device further away from the engine you are monitoring. I plan to do this with my small outboard so I can monitor it more comfortably as I go through the engine break in procedure with progressive rpms on my new 2.5 hp outboard.

## Questions & Answers

**Q: Why does this only work for 2 cylinders?**
A: It works in three modes for the spark 1P1R (1 pulse of electric power thru the plug wire for every 1 revolution of the crank) ie… a two stroke motor, fires on every crank revolution… 1P2R (1 pulse of electric power thru the plug wire for every 2 rotations of the crankshaft) ie… a four stroke engine… and… 2P1R (2 pulses of electric power thru the plug wire for every 1 rotation of the crankshaft) ie… multi -spark ignition (usually CDI ignitions that require a battery to operate) 2 stroke… lastly, the hour meter doesn’t care how many rpm or strokes or pulses, it is just a cumulative timer of how long the tach has been receiving a spark signals off of the plug wire… number of cylinders doesn’t matter because all internal combustion engines will fire all cylinders in either 1 (2 strokes) or 2 (4 stroke) rotations of the crank shaft no matter what the layout is (radial, inline, V, horizontal opposing)…

**Q: Hour/ tach meter recommendations for a 3 cylinder motor?**
A: You need the HR-8062-2 model, up to 8 cylinder engines..

**Q: How is this one-wire tach different from others that have black, red & black wires? I want to use one to tune a mower, tiller & chainsaw.**
A: Just wrap the wire around the spark plug wire and that’s it, this tach comes with instructions how to calibrate it for one or two cylinders.

**Q: I purchased this. says for 4 stroke engines.has to be attached near coil. i cant to that. will it still work on my champion 3500 generator?**
A: Yes I have one on my champion generator works great
