Yesterday while running WOT I noticed my rpm's at 6000. I always check my guages while running so I know this just happened. I have a 1998 Mercury 125 HP normally taching 5200 - 5400. I came off plane and started back up and all was fine. Several times during the day it happened again. My question is, would I not have heard a change in the motor if it was indeed at 6000 rpm's. Would I not have noticed a change in performance at 6000 rpm's. If a tach goes bad do they surge like this ? I am ruling out prop issues as it will read high in nuetral sometimes. I am thinking bad tach, bad sensor, bad voltage regulator, motor problem. Anything else I should be looking at ? Thanks in advance. I know someone on here will have an answer for me. You guys are the best source of information anywhere.
