Sorry should clarify that, haha. I got to MA Maritime Academy, and one of the classes we have to take is internal combustion engines. So we have a lab that has the same engines as the lifeboat engines that we learn how to work on, disassemble, then reassemble and start. Im sure if we actually tried to use them to power something now they might not last to long or have other problems, but they always start right up when we reassemble them...correctly.
