what we dont know nick is your prop size and shaft diameter

shaft howl (Caused by the shaft whipping)can be a damn nuisance and it means accelerated wear. Ive always had a resonant growl on Sula and it has nothing to do with lime scale!

it was minor with the YSE8 and 2 bladed prop but since I went up to 13 hp and 3 bladed it ,means that over 5 ish knots under power isnt really on, and over 5.5 under sail the shaft HAS to be locked

It's more to do with the shaft flexing and the only cure is a stiffer shaft

there are other causes of course, like engine/shaft out of alignment, bent shaft's and all sorts of other fun things
