A friend of mine dropped of an old Mariner 25 today and wants me to see if I can get it running for him. The serial number tag is gone. It appears to be one of the japanese built Mariners but im not sure if there is a way to determine the model number so I can order parts. Its definatly not one of the Mercury made 25s. It appears that most of the carb kits and impellers are the same for these except for the very early models. This one is tiller handle with electric start. The cowling has a metal Mariner emblem on the front with the "Mariner man" on it. Any ideas?
