Re: what size castle nut
Hard to imagine anybody hauling a boat to simply replace a prop nut.

Re: what size castle nut
I have a diver who showed up to check props and replace zincs and nuts (long story). Showed up without a tank… I wondered… he masked up, went under, came up in 30 sec, picked up the nut and wrench, went down again. After a minute I was wondering; after a minute and a half I was worried… a shade after two minutes he came up like a porpoise, took a breath, came up 90 sec later and the job was done! Best diver I ever met. It was a site to see…

Maybe it's just me (and I am certainly biased) but if I'm a boat owner, I want a diver who doesn't have to rely on holding his breath to get the job done and done right. In the hull cleaning business, breath-holders are typically not well regarded. Nothing against your guy. It's just not the way I, or anybody who works for me, does business.

Re: what size castle nut
Oh, he could have strapped on a BC; he's an old hard hat diver turned SCUBA… former special forces if memory serves; I think he just likes to show off his 3minute bottom time! It was only a 2 minute job but most guys would have had to suit up. And I agree on bottom cleaning; even if you could do the job as well it would take twice the time! (and time is $$)

Re: what size castle nut
I didnt have any tanks, just a mask, wet suit and fins,no weight belt! Anyone doing this should at least have some weight..I have to admit that I would not be well respected by the pros(my hat is off to you)each time I came up for a breath I would hoop and holler ,shake, shiver and cuss,outloud! I did tie the wrench to a line then to a wrist strap I scavenged from my short board..I think it took 4-5 dives and I was sailing by noon..

Re: what size castle nut
The secret is to be properly dressed for the conditions. A light surf suit is probably not going to cut the mayo for most people in sub-60° water. When you work in the water for a living, being uncomfortable means decreased productivity.
