Crusing down canal, lost power but didnt kill. Starts and idles fine,gets up to 3,000rpms but wont plane.
Had same problem with another 225 pro max and was the idle speed controller pn 87076A10. I dont see
one on this motor, and how can I check?

Turned out to be a bad powerpack. While it was at the repair shop I made them swap my lightweight flywheel for a
stock one and switched to gap plugs from gapless ones. 60 seconds from the launch melted #6 piston.
