It was running perfect throttle was open all the way. I trimmed it up and it starts bouncing It bounced started to trim motor down and it doesn't die but it won't go any faster than idle speed. Is there a safety mode it puts itself in that has to be reset ? Any help would be appreciated . Thanks
 
It is look to be over heating , did you noticed any buzzer or any light on panel. If it is over heating you will get continue buzzer and red overheat light,then computer will automatically bring engine RPM down to protect the engine. that is why you see engine bouncing due to ignition cut of some cylinders.

once engine cool down, off the engine and restart the safety mode will deactivate.

Thanks for your suggestion but no it was not buzzing . I. Trimmed it up to and it was cultimateing or bouncing the faster I went and I trimmed it up and it the faster I went the higher it would bounce. I was adjusting the jack plate.
 
What is the WOT RPM did you get ? And after what RPM it bounced ? Is this new modal BF40 (EFI) ? May be while trimming it is Over Rev...
