OK boys! My first post here from a New One to his first Airboat. Can tell you I have a 12' boat with a 4 cyl Continental aboard. But what Cont. and where to find the engine ID on the motor is a mystery. Help? I do know it's an Airboat! Makes alot noise, and blows my dog off the dock. Soooo. Can only be 1 of two 4 cyl, correct? How do I tell?
