That page may be different for each person. You may have an outboard, me an inboard....you a race boat and me a cruiser. In the middle of what kind of situation would I need fast advice? but not too fast cause I would have to go read that one pager. I think most captains have a log book and more than enough info they need in a binder...IE: oil filter make, engine belt size, emergency procedures for guests on board if the captain gets ill. I know I do, and I had to make own spreadsheet using the info I researched here.
Maybe you want to start a thread asking about which specifics are most important on our list and make a one pager from that?
