I have an 82 Glastron 19.5 ft deck boat(SV-191). It has a Merc 5.7 and a merc "1" outdrive. I am unsure of the gear ratio and which prop I have. Can You guys tell me my gear ratio if I give the outdrives serial number? Also, the only numbers I see on the prop are a series of numbers near the hub. Are these the numbers that identify what prop I have?
