At WOT the Starboard motor will turn 5400 and the Port will only turn 5000. The Port motor is the staggard one. The motors are 2006 525's. The props are the same and have no dings or nicks. I have taken the Flame arrestor off and it seems like the throttle plates is opening all the way.

ANY IDEA'S ?

Check to see if you have any fouled plugs.. I had similar discrepancies and 3 were fouled out. Carder

Problem with the drives? Swap them to check for parasitic drag?
