Hour Meter / Tachometer - WORKS with 2 Cylinder engines UNIVERSAL Digital RPM Gauge Back-light Display for ATV Dirt Bike Outboard Yamaha Honda KTM Polaris Engines Generators Boats Motorcycles Scooters

Added this to my new zero turn mower. Easy to install and works great.

Works as advertised. Definitely isn’t waterproof though. I use it on my jetskis and after a while it starts to fog up. Otherwise, works great for the price and a great tuning tool for 2-Stroke motors.

Works great.

Some reviews mention this unit's inability to repel water. They are correct. Idk what IP65 is supposed to mean. Apparently it means if you sneeze around it, the screen will fog up.I spray off my mower after every use. I figured the garden hose wouldn't bother it. I was wrong. Luckily for me, the condensation went away. Now, I NEVER hit it directly with the hose. It get a little incidental splash, but nothing direct. So far, that's worked out ok.

I have 9.8 Tohatsu four stroke outboard. the reading for max rpm is not correct. this engine fires both plugs at same time. there is no setting for this type of ignition. idle is close, hour meter is correct. if I double max rpm it is in the ball park but not correct.

The product does not meet its specs. The display fogs up and become unreadable. Moisture is becoming apparent in the display and over time will fail the unit. Do not buy this product.

Easy enough installation. Calibration was easy enough without instructions.Worked great for a year. Had to change the batteries. Make sure you use some sealant when you change the battery. It never worked again.

Cool but not very accurate
