Review: Just what I was looking for! - Worked as described. Installation was easy no wire splicing or anything. Haven’t had it long enough to see the battery life but would assume it to last quite a while. Love that it offers rpm’s along with the hours. Overall a great product and I recommend it for anyone looking for anything along these lines.
Review: upgrade - this was a easy install even for a 14 year old and looks pretty well made.

### ⭐⭐⭐⭐⭐ Just buy it , it’s worth it
*by C***E on April 12, 2026*

Product works well for my 2 stroke outboard . Easy to use , easy to mount , the cord is not super long for an outboard motor if you wanted to mount it outside , I like that that battery is easy to swap out an is not a disposable unit , I will likely buy another for diagnostic uses
