Re: Replacing propellor in the water?
There is no reason you could not do this in stages with a mask if you have a prop puller. No SCUBA gear required.
Having done many dozens of prop R&Rs underwater, I can't say that doing it without air would be much fun.
You really can't accomplish much if visibility isn't around 5' or so.
And this simply isn't the case.
