Hey there. First post in these forums, although ive read lots of posts in the past for info on maintence stuff. Just trying to id my merc 402. The serial is 7177879. Ive been searching around quite a bit, and cant find anything on it. The serials for this model seem pretty confusing, with some early years running al the way from 3xxx to 9xxx. Any help is greatly apreciated. Also, had a quick prop question. Just wondering what the most pitch i can get for this motor is. Im going to be pushing an extremely light 11 foot boat, so i dont want to over rev the motor. Ive found 17 pitch, but was wondering if these props are at all interchangeble with bigger HP's, and will getting a bigger diameter help me? Thanks in advance.
