When I first got her up on the plane, there was only a slight noise which disappeared completely once on the plane. I actually ran it all the way to wot 4,900 rpm's, for a couple of minutes and it sounded sweet. Backed her off and then getting back on the plane, I could hear the noise again, perhaps a little worse, so I headed home. She ran beautifully at 3500-4000. Just cruising, so I was on level trim and a straight line to the marina.
Approaching the marina, I slowed down and the noise was getting worse so I tied her up, scratched my head and called it a day. Aussies are good swimmers anyway but I my wallet may have needed a life jacket.

Uni-joint and yoke appears OK but even I knew something was wrong when I saw these little round things lying on their backs inside, in a puddle of water......
Gimbal bearing has died due to a small split in the bellows. They're coming back later today with more tools to remove the gimbal bearing. Meanwhile, the drive is going back to their workshop to give it a thorough checking.
Im not overly impressed 'cos when they serviced everything a few months ago, I asked them to check anything that could be worn/damaged and that should include the bellows. Oh well, could be worse......

Dropped back this avo' and they have removed the remains of the old bearing. I haven't spoken to the technicians yet but it all looks pretty normal to me............ Thais tend to fix the immediate problem and not always investigate further and I don't know enough to argue about it. They said they doubt there's any further damage so I pretty much have to go with what they say.
I felt like a marine proctologist taking graphic photos here.........

P.S. Top right of the 2nd photo, is that a rusted bolt head or just some rusty water and grease?
