Trying to verify my Teleflex tach readings on a 2015 Mercury

Customer Question

Trying to verify my Teleflex tach readings on a 2015 Mercury 60 HP 4-stroke so I can determine a new prop accurately. Using a Echo PET-1100 Engine Tach and running the motor with muffs I get the correct engine RPM at idle, 720 -730 rpm and readings that exactly match my Teleflex tach when I have the Echo set for 4 stoke/3 cylinder??? Please explain?? Thanks
