Oil ratio older Merc?

[Anonymous]

My nephew and a friend picked up a mid eighties Mercury 135

Oil injected Black Max.

The oil inject has been disabled and he want’s o know the oil/gas

ratio to run it at . So far they’ve been running on what’s in the

tank while getting it to run.

Thanks for any help.

Can anybody tell me why i get double spaced when I

post on this site?

I’m almoost sure it is 50/1 ratio. Those oil injected motors ran very lean on oil while idiling but when you slam full throttle they starve for oil waiting for the electronics & oil pump to react. Very hard on the motors.
