I spent 3-4 hours on the lake this past weekend. Still did not achieve the WOT that was expected only got 3200 rpm. I pulled the plugs today to get an idea of what I was doing. 1& 2 showed evidence of carbon fouling #3 was clean. How do I interpurt this sorry for the spelling. |

OK changed plugs fron NGK something to Champion QL77's carried the boat to the lake so I could change out bunks easily. Of course I had to run up the lake for a bit ran smooth got to 4000RPM's do not have TnT I wonder if trimming out the motor with the manual detents would help reach 5000 RPMs |
