When a marine head goes bad there is usually a story to tell, and it’s never a good one. A clog or a leak can ruin a weekend. Even a properly working head can be awkward to explain to guests, “Well, you do your business, flip this lever, pump this lever and then don’t forget to flip that lever back or you can sink the boat!” Invariably, the guest has a problem. Often they ask for assistance that is neither fun to request or give. Or worse, they don’t ask.
