for all of you watching this make sure you are across the latest service bulletin for these props. They have a propensity for spitting the dummy and the manufacturer has a workaround with different washer and nut. Critical issue - find the service bulletin
Interesting that you should say that as sadly a diver was killed by a Great White just a few months after the video was made, literally a stone's throw away! It was filmed in Tasmania.Thanks for the comment.
Nice job from the diver but a very long and difficult job underwater, also unsafe with the lack of glue and split pin. It will need to be reinstalled on the dry to avoid losing another prop
Thanks EWOL. It was a quick fix to get the yacht back to its home port in Hobart, so a matter of a day sail. The yacht was then slipped and the prop removed and refitted dry with loctite. From memory there was no hole for a split pin, not sure if one was drilled when slipped. The dive job was well planned with each component bagged and in order with a thorough understanding of the instructions prior to entering the water. It took less than an hour to complete the work.
wow. good job. never would have thought of the umbrella (i thought it was garbage drifting by. would a magnet tray of helped, or all the pieces/tools non magnetic?
Hi Chris, thanks for your comment. All components were brass for corrosion purposes so not magnetic. There are probably better ways, but the old beach umbrella that I had in the shed did the job for me.
RoboTekno I'd imagine not, unless there was very infrequent use of the motor, even so, any fouling would soon be crush and shaken off when the propeller was operated.
Bad idea! Sticking a big Seagull on the back would get the boat to the slip. Alternatively a much less expensive fixed propeller would do the job. It is also possible to obtain stiff nuts and stiff bolts that are pre-loaded with a plastic coating. Another way is to coat the bolts with Loctite on dry land then fitting them after allowing the Loctite to dry. This is a way of making ones own stiff-bolts. Incidentally bronze and aluminium are a bad combination regarding corrosion.
+Tech Davey Thanks for your comments and information. I'm not sure if it was a "bad idea" as it worked perfectly and the prop was refitted dry (as per manufacturers instructions - with Loctite) soon after return to the marina where it was, on slipping, found to be completely intact and all components still appeared to be as tight as when first fitted. There were geographical and navigational reasons behind the decision to fit the prop underwater and your alternative options were discussed prior to the decision being made. I'll look into the corrosion issue and pass it on to the yacht owner, but if you'd like to reply with some information on the potential issues it would be good to read and it might also be useful for other readers. Thank you.
Nunca un paraguas en mi barco, pero es buena idea usarlo debajo de el. Magnifico trabajo del que todo es aprovechable, Peixe Porco. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BrGVzJLHkOk.html
