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. ## Features - Works with any gas engine up to two cylinders and 16,000 RPM - Adjustable input for all types of ignitions, including fuel injected engines - Hour meter shows total hours accumulated; hour/tach meter shows RPM's when the engine is running - Easy installation; no power or ground required - Internal battery lasts up to 10 years - Instillation wire is 14 inches long ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000FOOAXY | | Batteries | 1 Lithium Ion batteries required.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***Y on 13 June 2022* 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 *by S***Y on 18 July 2022* Great product!
