The generator on Sea Dragon is a pernicious beast, a result of taking full advantage of the available space, which leaves next to no room to actually work on it place. Instead, once a year we spend 4 days or so dismantling the walls and ceiling, hooking up block and tackle to overhead beams, and after unbolting and disconnecting everything connected to the generator, haul its 400 pounds out of the engine room and lower it into the hallway where we can easily access all sides of it to check that all is well.
