First time here so be gentle. I have a 1964 40hp model # RDS72 Johnson outboard with hydo electric shift. My problem is the wires from the controls have been cut and I dont know where any of them go.The motor runs like a top( hot wired around to start it). I dont know if there are any problems with the unit. But I did find a crack in the lower unit and when I drained it water ran out mixed with the oil. Do you guys think it is shot and needs replaced or can I fix it. Have not opened up lower unit yet but mostlikely will need to to clean it up.
