'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.

I would assume 50:1 but call the manufacturer to confirm
