USA HR-8061-2 Inductive Hour Meter & Tachometer - Waterproof RPM Gauge for 1-2 Cylinder Gas Engines - Fits Dirt Bikes, ATVs, Outboards & Generators - HR-8061-2

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.

Solid, shock proof, waterproof, accurate and simple to attach. Well pleased 👍

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.

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

Bought one for a mud motor on a boat, worked great for 2 years uncovered out in the elements, then the button became a little difficult to function, took the rubber button out and was still able to press the board button with a tiny flat head screw driver. Documented 200 hours and 2 years in the elements is pretty good for the price, especially compared to some of the others on amz. Never had an issue with water getting behind the screen or the battery dying. Bought a new engine and replaced the old meter with a new hardline tac/hour meter. Going to keep this engine covered when not in use so this meter should last me a long, long time. Also gave the old meter to a friend who is also running a mud motor on his boat and he is still able to enjoy using it to keep track of his hours and rpm’s. Best tac/hour meter available on Amazon hands down.

Works perfectly highly recommend

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.

While more expensive than I really wanted, these are very easy to install and do a great job. The provided wire was much longer than I needed and the instructions didn't tell me I could cut to length... I did anyway. The meter can be tape mounted or attached with screws so being on an outboard motor, I opted for the tape. It's well worth the money to accurately be able to keep track of hours for proper oil change intervals... I added 2 Yamaha engines to our fleet and it surprised me how much difference there was in three weeks of use, one had 69 hours while the other had 130! Had I been guessing, I'd have had no clue when to change the oil.

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.

Not that hard to install. Shows me everything I need to know, including maintenance intervals. I have this Hour/ tach meter fitted to a Honda mower.

excelente contador, instalado en el chasis de una maquina de perforar, 850 horas y continua operando en condiciones exteriores y de contaminacion.

Product is shipped in reasonable time. Works as advertised. Convenient and cheaper than importing it yourself.
