Well the title says most of it but .Anyways I have a friend that has the 90 HP jet.we took it out the other day and runs fine for about 10 minutes (until it gets warmed up) then it seems to go into a slow mode!Stator and trigger were recently replaced.Getting good fuel and coils plus compression checks great.It seems to me like there is something electrical.It will purr like a kitten but will not go over 2800-3000 rpm?No spit or sputter.The oil mixing unit was removed a long time ago which I know some motors will idle down if it faults so that's not the issue and its getting good water staying cool.Help me out guys???
