A manual is like having a tool for every job you could encounter on your golf cart. The manual covers a wide variety of different aspects of the EZGO that you may not have known about in the first place. This is an OEM manual, not an aftermarket replacement, so first and foremost, you will get diagrams and procedures that come straight from the engineers at the factory.This E-Z-GO Marathon Service Manual will take the somewhat proficient weekend warrior and allow them to service his or her golf cart with ease. The great thing about these little books is that all of the parts are labeled with the OEM numbers. You can Call Buggies Unlimited for help in crossing them over to a current part number that we have in stock. This is a special order item because it has to come from EZGO. Please allow up to a month for delivery. Most of the time, they come in much quicker, but we like to underpromise and over perform.
