Greetings,
Mr. GC. Well, high to low pitch definitely, as you have surmised, has something to do with the drive train and the prop winding down IMO. Sooooo.....cutlass bearing, stuffing box, transmission. Don't discount the stuffing box so readily AND it's the easiest to check. Could be running dry. Is it warmer than usual?
