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.

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.

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
