In reverse my 20hp Johnson came out of the water in reverse because in did not have it locked and possibly over reved . Two issues, oil drained from middle lower hole on shaft. This appers to be lower unit oil. Might need to replace seal? Bigger issue I have no spark. Moter ran great before this. Fuel and compresion ok. Electric keyed start cranks over fine. Points and condensors visaully look fine. Where to go from here? Is there a kill switch? And if there is, where is it, and is it resettable? model 20R73-A or 20R75-A ser. E332735
