the proper mix is 50 to 1 or 16 oz to every 6 gallons,in my little boat I put 4 quarts in the 48 gal tank and its been running for 22 years,your running way to rich and your plug is probaly fouled,take it out clean it up/dump your fuel and mix it right,thats a great motor you got,I hunted with it for years,oh yeah when you get started run it till all the smoke is gone or you will have carb problems ,if you dont have them all ready,a little carb cleaner wont hurt but get it running first,or all that trash will foul you out,have a great trip bartriley1

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
