Bought a boat with a 25hp Mercury on it. Want to start going through the motor. Serial number 5943879. 1983 maybe?? Anyway I cannot find a carb rebuild kit on the net. Can someone please advise me as to the correct kit number I should be looking for and where on the net to buy it. I appreciate any help so much!!!! I want to get this motor in the best running condition I can and since it has been sitting for a few years I am just going to go ahead and rebuild the carb. I cranked it just to make sure it does run, but it needs some work to be reliable for my family.
