    whining noise in throttle

    sounds like the motor is overheating or oil pressure is out of spec. the noise and the limiting of RPM is to let yoou know the motor has a problem, and you need to look at your gauges to see what they tell you. and shut down when safe to do so.

    2008 90TRL need more power!

    there is no such thing as a 90TRL. is it a F90 TLR or maybe a 90TLR did this motor ever push this boat at normal speeds and RPM?

    LF225XCA Trim Piston Binding

    good to hear you figured it out, and thanks for coming back to say what the problem was. that was not something anyone would normally see. you had me confused about what you were calling trim and tilt when you said " trim piston binds immediately engaging in trim after tilt." trim is the small...
