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

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.

Replaced the meter on 2022 Bad Boy Avenger mower whose meter stopped working. Dealer wanted $79 for a new one. This won’t drop in original rectangular hole so I mounted it on top of hole by drilling two new holes. I cut the wire they supplied to about 3 inches and crimped on a female spade and then connected it to existing wire on mower. Took about 10 minutes to install.

This unit is easy to install and appears to work well. I tested it together using another RPM measuring device and it appears to be accurate. The two-sided tape that is provided is very, very, very strong, so plan out where you want to put the device well before you actually stick it onto your portable generator. This is because it may be very difficult to remove once you stick down the two sided tape. If I had to affix/position this again, in hindsight, I would opt to have the screen on top of the generator with the display screen facing up towards the sky. It's very awkward to crouch down to see the display on the device if you mount it on the side of the generator. So, in hindsight I would have picked a spot on top of the generator so that the screen faces directly up so that you don't have to bend down to read the screen.

Works great, everything I expected and easy install.

Super easy to install. Works well. Exactly what I needed to track hours.

I have had great luck with my tachometer. I have installed it on a 2 cylinder 4 stroke outboard, then later on a 1 cylinder 4 stroke Tecumseh snowblower. Each time I felt I got accurate results. Note: On the snowblower motor, I had to set the setup to 2P-1R which to me wasn't intuitive. I thought this might help someone out.

I now own 4 of these high quality, really handsome, one-wire Tach/Hour meters, that were easily installed by either a drill-and-screw-on -or- peel-and-stick-on placement. Sadly, I wasted $$ on other Tach/Hourmeter brands sold here in this price range (and much cheaper) that all have wildly inaccurate Tach readings, less features and, I now know are not as classy looking as the HR-8061-2. After not being able to get stable or accurate Tach readings on those "other" poor performing units, even after trying other selectable firing intervals, 2, 3, 4, or 5 turns of the sense wire neatly coiled around the sparkplug wire, in BOTH directions from the sparkplug(!) I finally tried this more expensive HR-8061-2 meter. This Hardline Products device shows (engine stopped) with press-and-hold in Tach mode the Max RPM -or- with a press-and-hold in Hours mode the "Number of engine starts", with the MaxRPM being able to be selectively reset each run time by just continuing to hold down the meter's single button.Installed when new on my 4 year old log splitter before ever starting it showed 71 engine recoil starts, reminding me how many days of work and juice/water breaks I took. On my 4-stroke engined weed wacker, besides being priceless to keep track of the run times for engine oil changes, the maxRPM showed 9,860! One unit on each of my orange 2000W and yellow 3100W Inverter Generators ACCURATELY shows a stable, unchanging RPM reading when the engines are running steadily under a load. Being that you can access the hour reading (say, 48.1) with the engine running, re-fueling or oil change due data can be recorded or acted upon. As a 70-something retired career MotorCycle (Car/Truck/PowerEquipt) mechanic, take my word for it, this is the ONLY Tach/Hour Meter you should invest in.

I needed a tachometer to set the idle rpms on my motorcycle, a 2005 Yamaha Road Star Silverado, which doesn't have one. I didn't want to spend a bunch of money on the high dollar tachs since I mainly wanted it as a tuning tool. So I priced a bunch of different inexpensive ones, read all the reviews and the Hardline seemed to consistently get the best reviews, so I got it.It's super easy to install and so far seems to be pretty accurate. After setting the idle rpms I took the bike for a ride, making mental notes of my rpms at different speeds while running in 5th gear. Then posted my numbers on a Road Star forum and people said my numbers were spot on.Since I purchased this as a tuning tool, I hadn't planned on leaving it on the bike. But when it was all said and done I decided it was pretty nice having a tach. So I made a little bracket and mounted it to the left handlebar. Pic was taken with the bike off, so the rpms aren't displayed. And I'm not concerned with the Hour meter, so I've never bothered to set it.As far as waterproofness goes, I haven't really put it to the test yet other than to wash the bike, which didn't seem to hurt it. But the entire unit seems to be sealed pretty good, so I don't anticipate any issues.The only real issue is that it's disposable.Since it is sealed, once the battery dies, that's it.Overall though I'm very glad I purchased it.And it's definitely served it's purpose. It may not be the classiest looking tach, but it works!
