With your lower unit off have someone shift the engine into forward while watching the gear shift select shaft's rotation,let gearshift remain in forward,now place your lower unit in forward and reinstall. In the future just put engine in forward when installing a water pump as there won't be a need to move gearshift
SOURCE: 40 hp mariner outboard 2 stroke oil leak at
without seeing it in front of me its difficult to advise,i had a mercury but it wasnt oil injection so i iam not sure exactly how this injection system works but i should imagine its nothing more than a O ring thats perished or a copper washer needs cleaning with some wet and dry.I bought a new 4stroke mercury in the end because i got fed up with fuel consumption from the 80hp two stroke ,this four stroke 50hp will do about 12 14 nautical miles to roughly 6/7 litres of petrol at about 1200 rpm because iam only a sunday driver and the bumping on the waves makes my back ache unbearable,Well this is the land of fiesta /siesta /manaña --spain .Have a closer look and see where its leaking its only a mechanical pump running off the engine ,so it will have a push rod with some sort of diaphragm that pumps a tinysquirt of oil into the crankcase so it can mix with the incoming fuel ,nothing complicated

If you know the year you should be able to go to http://www.crowleymarine.com/parts.cfm and pull up the wiring diagram out of the manual.
SOURCE: outboard motor won't run under load
I have 1969 5hp Johnson. Starts and runs good, but will only push a 14ft row boat slow at low to medium rpm. When at higher rpm the the motor just revs up and the boat slows down to almost nothing just like it has seaweed around prop.Any help would be great.
