Hardline Products USA Inductive Hour Meter for All Gasoline Engines – Waterproof Maintenance Gauge for Motorcycle, ATV, PWC, Boat & Generator – HR-8063-2

I installed this on a compressor connected to a Honda GX200 motor so I could track surface on both the motor and the compressor. I have been using it for about 5 months now in tropical and subtropical conditions. High heat and humidity. The display is still easy to read, but that may be because I keep it covered when not in use. Works great, easy to read. Now I can complete service without having to mentally guess how long it's been since the last service. I should probably buy these for my outboard motor and suitcase generator also. Should work on anything with a spark plug.

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.

Easy to install on Toro Zero Turn mower. Works just fine!

As described. Installed on a Simpson/Honda-GX390 pressure washer. Works great.

I installed on a new quad that didn't even come with one from the factory... that's another story. I could not wait to install it properly before I did the break in on the new quad, so I just tied it in knot around the spark wire just before the plug boot, and it worked like a champ. There is a little icon in the left side of the screen that blinks when it is running, so you don't have to wait 6 minutes to see if it clicks over .1 hours. The unit is sealed and you don't even need to strip the cover off the wire on either end. I did do a more permanent install with wrapping it correctly around the spark plug wire, and securely running the wire to a permanent location under the seat were the unit is now mounted. To clarify, it states "no wiring necessary" but you do have to wrap a wire around the spark plug wire, and you just slip the other end through a hole in the bottom of the meter, it comes out the top, bend the wire over and into another hole in the top, pull tight from below, and your done.

I bought a new boat recently with new primary and new kicker motors. I installed these so I can keep track of hours for maintenance. Installation was very simple... just wrap a few wraps around the plug wire, zip tie it off so the wraps don't unravel, and that's about it. I've checked the meters several times over the course of summer and this fall, and so far they seem to be keeping accurate count of hours on each of the motors. The only con to this item as well as many others is that the manufacturers do not make one with an easily-replaceable battery. Once the battery fails, you need to replace the unit. I'm not sure if this unit uses non-volatile memory in the event one does try to break open the case and attempt to replace the battery.

Great product easy install and now I know hours on motor.

Quality company. My unit did fail after a few years. Easy to contact them and the stood behind the product - I had a new one in two days. I paid more because this was made in the USA - glad I did!

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.

Work perfectly , easy to fit .

Easy to install. Great for monitoring hrs on small motors which don't have electric start.

Fonctionnent bien facile a installer

The hour meter has two mounting options, screws or double-sided tape. I used the tape as I was mounting on the top of my generator. Install was done in under 5 minutes, most time was spend drilling a hole for my placement of the meter.
