I installed this tach/hour meter on my Suzuki DF 2.5 outboard. It was easy to install by simply coiling a wire lead around the spark plug wire and you are good to go. It is powered by a 2450 coin cell. It seems to work well and appears to be accurate. Along with hour and tach function, it also has a service interval alert with a countdown timer that you can customize. I set a service alert for the first 20 hrs and then a second alert at 100 hrs. You can set multiple one time service alerts as well as recurring interval alerts. I hope this device lasts because I really like the functionality. These devices are easy to find on any of the big online retailers.
