Video of the prop cavitation

My significant other half bought me a aquapac type waterproof camera case for around 16. So armed with this and my compact camera I set out to do some underwater filming The prop has been making a noise and i thought it might be cavitation. What do you think?

Well I thought I would hold the camera underwater and gentle increase the speed, this didn't go to plan and the second attempt my mate opened the throttle fully which took me by surprise good job I had my arm through the A frame

The language is a little bit descriptive so turn down the sound down if you are a miner or a sailor

Me too, perhaps attaching it to a pole for the next attempt may be wiser...

Yes, I agree it does look a bit dangerous but the camera was held against the tube and never any lower than the hull of the boat. The film that you see was the results of many trials to get to this point. I was on a short harness and my arm was through the A frame. My hands were more than a metre short of the prop. So to summerise reasonable precaution were exercised, the only thing that was unexpected was my mate suddenly opening the throttle which was not part of the plan. This resulted in me getting wet.

I would not recommend any one else doing this with out fully assessing the potential dangers. Kid don't do this at home moment come to mind.

I hope you enjoy the video.

Something 'unexpected happening' (ie an 'accident' or a careless 'mate') is surely why there are guidelines (common sense??) for keeping away from props whatever you're up to...

I do agree with you

I did realise that it wasn't the brightest thing to do. Therefore I would not recommend anyone else doing it.

Lol, Depends on the pole I guess

Let me rephrase, perhaps next time attach it to a short pole.... Now I'm being discriminative instead, is that better ?
