Hi guys, I'm new to the forum and new to boat ownership. I just bought an older, but decent shape, flatbottom that came with a 20hp Mercury 200 with Thunderbolt Ignition. First of all, I know virtually nothing about the motor. First of all, I can not even tell you if it's a 2 or 4 stroke motor. There is a serial number on the bracket that mounts the motor to the boat. It reads 4105056. Can any of you experienced folks here please tell me what it means? Also, if it is a 2-stroke, what is the fuel mix ratio?
Thank you much for any input!
