Thanks, guys.

I'm using the same term, "singing," that my hull surveyor used. If I remember correctly, it was a rhymic thrumming sound that rose and fell in volume, but never very loud. You could only hear it--and then pretty faintly--in the aft cabin when standing on the starboard side. He speculated the cause might be a strut bearing and recommended getting it checked and maybe getting the prop indexed next time it was on the hard. He did not seem to think it was a major problem.

At WOT, with eight adults on board and the synchronizer off, the port engine got up to 2,370 rpm and starboard maxed out at 2,417. We used a local marine diesel mechanic who had a lot of instruments hooked up. He also inspected the linkages and said they were adjusted properly.
