My 2007 Yamaha 90TLR will run perfectly for the first few miles on the water. Once warmed up, if I leave it at WOT for a little while the engine bounces back and forth between a lower and higher RPM. It sounds like I am blipping the throttle, and it slows the boat down until I back off the throttle then slowly reaccelerate. It will run WOT again for a little while then do it again. It does not give me the issue at lower RPM, only at WOT and just below WOT. Only seems to do it after running for a while; not for the first five-ten minuets after leaving the dock. I have not been noticing any alarms. Seems to do it no mater the engine trim angle.
Curious if any of y'all have had the same issue or know what the issue might be. Sounds like it could be fuel delivery related, but I don't want to guess just throw random new parts at it.
Also, any recommended Yamaha mechanics between St. Augustine and Daytona Beach? Looking for a tech that does good work, and is honest. Might have to go that route if I cant figure out the issue myself.
Sorry for the vertical video. Video starts with the engine "bouncing". It self corrects, then starts bouncing again around 17 seconds.
