Review on πŸ”΅ Jayron Tach Hour Meter: Digital LCD Inductive Tachometer, Waterproof Design for Gas Engines - No Battery, Powerful Timing and RPM Measuring - Perfect for Lawn Mowers, Motorcycles, Snowmobiles, and Generators (2/4 Stroke) (Blue) by Justin Fletcher

Revainrating 1 out of 5

Will not work with Yamaha 25hp outboard motor.

Purchased to determine max RPM for proper propeller selection. Came with no instructions on how to switch settings to 2 cylinders 2 cycles. It seems that the tachometer shows twice as many revolutions. On the back and in the picture is a 2P1R setting for a 2 cylinder 2 stroke engine but I couldn't find how to change it. No support to contact the manufacturer

Pros
  • Top marks for support and durability from testers
Cons
  • Compatibility
