The kit eliminates the guesswork in trying to identify the parts and part numbers needed and verifies that the components have been checked to fit the specific revision of the generator set. When certain items are used they can be replenished as needed. The sturdy container can also be used to store additional parts related to the boat's electrical/machinery system. Part numbers of each of the components in the kit can be retrieved from the maintenance label on the generator set.
