I built the outboard last year, and used it last summer, despite the noise.
Just as noisy in operation with the prop installed and pushing our pontoon boat.
Decided it needed to get fixed somehow otherwise it is pretty useless.
Mentioning your motor is much quieter helps, at least affirms there is something unusual with mine.
I have wondered if I got the phasing wrong by mis wiring whether that would cause a high motor noise.
Not something I want to experiment with, thought, without some certainty it might be the issue.
The increase in noise at about 4000 rpm is concerning, because that is well within the motors limits.
