Not sure how much work I can do on my F200 if it stalled out on the brine. Yes I do all my own mods but apart from checking wiring..electrical shorts breaks etc. fuel issues, mechanically I do not think I could do much. They are a fairly complicated engine, (from my humble perspective) especially if one has to lean over or stand in a splash well to do the wrenching. I understand carrying safety items in case of a hull breach etc. I guess my T8 kicker is my best friend out there although she would be a slow trip I trust it will get me home.
