Hardline Products USA Hour Meter (Hour Meter)

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.

So far, so good. I added this to a 37 ton wood splitter that has a crx 420 4 stroke motor on it. I mounted it on the plastic near the air filter, being careful not to drill into the air intake line. The RPMs were double what they should have been at idle but holding the button while in rpm mode fixed that to get to correct mode. I ran the engine for a bit to see the hour meter read 0.1. Seems good. Time will tell to see longevity. The first package I ordered only had the display unit. I returned that and got a package with display unit, sensor wire and zip tie. I cut down the sensor wire to suit my needs as the run was not very long.

Product was well packaged and appears to be ruggedly build for long term use. Installation was very simple on my Wen 2000 inverter generator and the fitment was great due to the small size of the display while still being plenty big enough to read easily. I was surprised to see that there were 2 resettable hour trackers which will make it nice to view total hours and time between maintenance.

Works perfectly highly recommend

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

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.

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.

Great replacement part for tach/hour meter on 2023 Bad Boy Maverick HD (Honda engine). Simply crimp a male Quick-Disconnect onto the new meter's wire and you're ready to go. Pic is of female end from the engine. Did drill two 7/64" holes in panel to mount the new meter but that's everything. Very easy and seems to work great! One add: be sure to check your engine’s pulses per rev and set the new meter accordingly.
