Hi All - I have a 1994 Formula 252 with a Mercruiser 7.4/Bravo 3. Engine runs great, but when the boat is up on plane, I hear a pretty distinct squealing sound at certain points. When turning the steering wheel at any speed besides idle, the noise is the loudest. When I quickly jerk the wheel to the right on plane, I sometimes hear it but definitely not as loud. Turning right slowly doesn't make any noise. I also hear the noise when raising the trim after the boat comes up on plane. Any idea what might be causing the noise? It seems to sound like a combination of a squeal and a whistling noise. Can take a video next time I'm on the boat if needed. I'd like to avoid just replacing parts until it goes away, so any guidance would be helpful as a place to start looking. Thanks, Greg
