Yamaha ENG-METER-4C-01 Hour/Tach Deluxe Engine Meter

Good quality. Screen is very easy to see. Installation didn’t take too long after watching a how to video. The last generator that I purchased I bought a cheep one of these (not YAMAHA) and the quality was not good and the screen was hard to see. Spend the extra $$ and get a good quality one like this. Yamaha puts out good products.

Installed the hour meter on my 90 Hp outboard motor. It is underneath the cover so it will be necessary to remove cover to check the engine hours for maintenance and oil changes. But at least I can do that now. Too bad Yamaha doesn’t provide one for the motor anyway for the cost of the motor itself it seems logical that it would have a meter for that.

I purchased this in conjunction with my Yamaha EF2400i generator to keep track of the hours for maintenance. Very easy installation. I decided to install it permanently on the front panel with the screws. I chased the lines through the panel, under the fuel tank to the spark plug wire. Everything is included for the installation. I read somewhere the sealed battery only lasts three years. Even at this, with a purchase price of $10.00 it will be a easy and inexpensive change-out for the next three years. Well worth the price. Less than an hour on the installation.

This device does not show runtime hours until you shut the generator off. In that way, I would rather have just an hour display than an hour/tach display. If you're thinking of keeping a runtime log and recording fill-up times while the generator is on, think again. After one year outdoors and only partially exposed to the elements, there have been no issues with it. There have been some difficulties with keeping the wire cable-tied to the spark plug wire but that's more my issue, I think.

I have purchased 2 of these for my two Yamaha generators. There are cheaper knockoffs available but this shows RPMs and engine hours. Works very well with only one wire installation. Can be velcroed or screwed in to mount on your generator.

This is the second unit I have purchased but this one is for my new generator, the first unit is on my 7 year generator and still functioning perfectly. Most of the other meters offer only hour tracking and not with a RPM display. I figure with a seven year perfect track record on my first unit why take a chance on another one.

I installed this on a new Yamaha 2000 inverter generator to keep track of the hours for maintenance. The RPM function is pretty handy also. Easy to install without cutting any holes in your new gennie case.

I bought this to use on a Champion 3100 inverter generator. Since the Champion has the same engine specs as the Yamaha (171cc 4-Stroke) I assumed it would work, and does. I mounted it on the rear of the Champion away from the electrical outlets and heat from the exhaust using body side molding tape. Works as advertised.

This one worked well. No issues.
