We set my prop at the #3 setting and went to the river.(two blades are at #3 and two blades are at 3 1/2 ) My deeep water cruise spreed was 35mph @ 3000rpm. My skinny water cruise was 26-2700rpm at 30-35mph. The boat had half a tank of fuel and two guys. The motor mounts worked great and my temp never went above 180 degrees. Once again I fouled a plug #8 and the tach would jump around when you got above 4000rpm. So my top RPM is between 4500-4800rpm . I do not know what is going on with this fouling issue because all the other plugs looked good except #7 looked carboned up. Can your magnetic pick up cause your ignition to do this? At this point I am thinking about changing the module, cap, rotor, plugs, coil, pick up and wires. The Tech is brand new so I know that is not the problem. The boat ran dry ground with ease and I never needed to go over 4K to break loose on anything. I need help finding this grimlen guys.
