my 2-stroke johnson does the same thing.
I understand what you are saying, but I was running WOT and trimmed the motor, and could actually feel the drop in speed. I then proceeded to watch the tach as I did it again, and thats when I noticed the RPM drop on the gauge itself. My GPS is running off of my Fuse Block. It is old, and probably needs some maint.Sonnysmarine said:The rpms are not really going down, just showing it on the tach from too much voltage draw, the engine has two sets of winding, in the stator, or for charging , and one for running the engine, voltage to the cdi box to fire the engine,.
True if running acc. off the key switch it will pull too much amps on the 16 ga. battery + wire,
