+1 for Bronze.
Are your anodes in good condition? If so, you don't have a lot to worry about - just keep an eye on them. Come next haul out
, get some bronze key material and make them yourself if you need to. If you've got a file and a vice, you'll bang them out in an hour.
I wouldn't worry about not getting the props off either; find someone in the boat yard with a nice bronze drift and just tap them out. Failing that, having the resident engineer
tap them out shouldn't cost more than a case of beer
