Fuel ratio is 50:1
more than likely 50 to 1
How much oil do I use per gallon of gas for a 40 HP Johnson motor
This engine should have a VRO pump and if it has been bypassed the mixture is 50:1
'92 Johnson 115s are VROs which will vary fuel"oil ratio if operating properly. At idle, should be the 50:1 std. up to 100:1 at WOT. Some owners bypass oil-side of balky VRO pumps and pre-mix. Pretty bullet-proof motor if no VRO problems and seasonally maintained.
The Johnson outboard models equipped with VRO, (varible ratio oiling), have an onboard oil reservoir. Use a good quality, TC-W3 rated, 2 cycle oil. It is also good practice to not mix various brands of oil in the VRO tank, as reactions of additives in certain brands can lead to filter gelling.

If not using the VRO system, a 50:1 ratio is required, this is roughly one pint of 2 cycle oil to six gallons of fuel.
