WOT for my boat is usually ~35 knots, this particular day it ranged from 7 - 19 w/o adjusting throttle, a very unsettling feeling - the engine's computer system was trying to compensate for the clogged injectors and was getting all screwed up, it is also believe that some of the debris was floating therefore affecting multiple injectors at different times.
