Hello. I just bought a new pontoon with a new Mercury FourStroke 40 motor. When in gear between 1700-2200 RPMs, there is a rattling/screeching sound that noticeably disappears when outside this range. It doesn’t happen in neutral and also doesn’t happen when trimmed up significantly.

Doesn’t appear to be the cover or latch since it happens even with the cover off and when ensuring the latch is secure.
I can contact the dealer, but wanted to know if anyone has a
quick fix for this issue. It doesn’t appear to have an impact on performance, but is certainly distracting and annoying. Shouldn’t be happening on a new motor!
