If you spin the prop by hand does the hub wobble?

Apparently they have a machine that can check the tolerances.

Cool. Sounds like you took a bit of a nasty knock. Was it loud and scary?

Certainly was loud. I instantly knew we had hit something as I was driving. My co pilot was not convinced. He heard the noise but though it was a mechanical noise. That made me think that he was right and the noise I heard which was like a loud click was something breaking in the engine. We stopped checked the prop for damage and plastic bags/rope but could see nothing. Because of the vibrations I then though maybe a spark plug had shattered but that was beyond being fixed in rolling seas miles from anywhere so it was limp back in to port time.
Its bloody annoying hitting something in the middle of nowhere. Close inshore you could understand it but 5 miles south of the IOW is a p___er.
Time to get a prop spanner and carry the spare prop for something that will probably never happen again. But better safe than sorry. As they say.

It was certainly weird.
As long as the Suzuki boys are happy with the shaft I'm going to be completely flummoxed as to how how something can bend one blade so badly and not touch the hull.
Its really strange. No visible damage to the prop unless you look at a certain angle then you can see that one blade has been twisted.

Was it a white bouy ?

Her indoors thinks it was a dolphin.

Certainly wasn't metal but what else leaves white marks and bends a prop ? Thats why I think a bouy did it.

Sorry to hear that your day was spoiled. I hope that the damage is not too bad. Do let us know the outcome.

Thanks for the pics!

I lost an entire blade of a stainless prop through tangling with a large piece of rope at speed. No visible marks on hull or anywhere else.

Did you get any vibrations ?

The prop doesn't look too bad. And the bloke I spoke to at Suzuki said "Of course it will vibrate". Thing is I've seen far worse props than mine and they haven't vibrated. I'm a little confused now. There's no sign of oil leaks. I'm going to swap the props over tonight and visually check the shaft. Suzuki said if the gearbox has any damage then that would be a major rebuild. Trouble is I can't check it without putting it under load at sea.

I think I'll just have to wait to see what Suzuki say but it would be nice if anyone on here has had vibrations after bending a prop, which has disapeared once the props been swapped. Much like running on three cylinders.
