I have a 40 hp Mariner built in 1988. Model 40ELO. this 40 hp mariner can be oiled automatically, which I do no use, or by just adding outboard oil to regular gasoline.
problem is i have lost both my manual, my notes, and my memory.
i need to know the correct Gasoline to Oil ratio for this engine. i want to remember 3.2 oz per gallon, but i also want to remember 50/1 ratio. a 50/1 ratio would be 2.4 oz per gallon. but for the life of me I cannot remember which I should be using.
Had the boat out just last summer, had no problems, but now have just completely drawn a blank.
What should I be using??
thanks for any help.
