I know this is going to be a hard one.
I have a noise / vibration that comes and goes under load. It seems to be related to running with the swell. Usually its there when first bring her up on plane and then goes away. Any ideas? Is this a prop starting to spin or the outdrive? Any suggests on props for DP's with a 41. I am running A5s, the boat came with a pair of used and new A3s as spares. The PO said something about having the prop resized and to have them checked every year.
