You can also get rumbling in reverse-only from the stern gland if it's not being properly lubricated. In forward, the prop thust pushes up against the end-plate, but in reverse the prop is trying to pull the shaft out of the gland ('tow the boat'), potentially causing metal-on-metal grinding noises from around the back of the prop.
What kind of stern gland has she got?
EDIT: The instructions on-line say the prop is water-lubricated, so ignore my initial question. They do seem to be rather fussy about thread lockling compounds though... I wonder if you have a screw loose? Unlikely..
I do wonder about the stern gland though. I was about to say Aqua Drive but duh that is the coupling not the gland. Memory fails me but it is dripless and I don't recall seeing any form of grease nipple. Hmm ... will check it out when next on board. I did btw give the gland a good looking at before we left the boat on Monday evening and there was not a hint of water coming in. Nonetheless the noise could well be what you describe.
