Generally 50:1. If the engine hasn't been run in awhile, I would run something more towards 30:1 for the first tank.
SOURCE: what is the correct fuel/oil mix for evinrude 4hp ?
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

Your best bet is ebay for a replacement user manual. Take a look around, you will come across one... For the meantime, gas oil ratio should be 50 parts gas to 1 part oil, i.e. 50:1. General care: Dont go full throttle for any length of time. Cruise of 3/4 throttle... Always flush engine after use in saltwater, including washing down exterior. Keep spark plugs in good order and check prop for fishing line wrapped around in near the prop hub. Otherwise, get a yearly service and have them check the water pump and replace as needed, get it tuned etc and gearbox oil changed.
SOURCE: cant find how to tilt evinrude outboard
have you got hydraulic trim/tilt? if so control button /switch will be on or near throttle handle-if not you will have to manually lift and insert pin at bottom of mount on transom

I own a small Mercury outboard so I did alittle reading in the manual and the ratio for your 86' 115 HP is 50-1. Hope it helps. Coach Theune
