The Whitby/Brewer has a large engine room, very large by sailboat standards. I, like all prudent sailors, carry out an engine room inspection every two hours, while motoring. Well..., kind of, sorta, when I not seasick, tired etc.. I always check when I smell something burning.
I have always planned to install some sort of video camera and knew that they had to be a cheaper option than the Marine branded ones for $400+. What about truck reversing cameras? Bingo.

If you have a MFD with a video input, you are good to go;
I already have White/Red lights in the engine room and will install a remote switch near the plotter.
