Re: Prop strut caulking?
If you're sure the strut is properly watertight on the inside, I'd use 4200 to fair it on the outside. If you peeled it off, with your finger, the surface probably wasn't well prepped. Be generous with the fairing. Most underwater parts call for 5200, which might be wiser. However, it's harder to replace and I don't think flexes quite as well.
