Our whine went away with...
Our whine went away only after Hunter sent us a new propellor. That was after all kinds of other shenanigans with hauling it out, sanding the propellor that came on it, disconecting and reconnecting the drive, adjusting the drip - I can't even remember what all they and we did to try to correct it. We were actually thinking seriously about giving the boat back to Hunter.Yes, it also had the whine while sailing, with the engine not running - scared us both, thought we really had a lemon. I think ours was between 16-1800 rpms while in forward gear. And higher when we slowed down from running it faster.When Hunter finally gave up - and it took lots of nagging from us - and sent a new propellor, the whine went away. They are investigating the propellor they took off - and I can understand why - the new one looks exactly like the old one.
