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

Prop shaft. You have to remove the bearing housing cap. reference number 70. Remove the bearing housing. reference number 60. The bearing housing will need to be pulled out buy using a puller. If it was in salt water it can be difficult. Pull the prop shaft and clutch dog assembly.

Are the controls for a 1998 15 HP 2 stroke Mercury outboard compatible with a 2011 30 HP 4 stroke Mercury outboard


If your old engine/control has the same 'options' as the30hp, yes everything is compatible... (Electric start or trim )
The throttle and shift cables are allways compatible...
