What is the mix ratio for a Johnson outboard motor?

Any Johnson outboard motor built since 1964 requires a 50/1 fuel ratio. Motors built prior to that date require a 32/1 ratio, with the exception of a few fishing motors built prior to 1955 that use a 16/1 ratio.

What is the mixing ratio for a Johnson outboard motor? - Mvorganizing.org

the manual shows for a 100 :1 mix the ratio is 4 ounces of oil to 3 gallons of fuel
there are two engines and one is 50: 1 ratio so that would be 8 ounces of oil to 3 gallons of fuel
there is a pdf version workshop manual at www.motoren.ath.cx and it gives the ratios for all of the 4hp suzuki outboards and the oil to use

check the oil pressure first with a test gauge, as far as the other light goes have you over revved the engine?

Please take a moment to rate my answer............Thanks

assuming you are not out of oil in your oil reservoir you probably have a bad sending unit in the reservoir. never bypass it or eliminate it as you could permanently damage your motor or ruin it if you ran it out of oil.

have a Older DT65 and the MOTOR is clean but wont tur over and sounds like a bearing in grinding or somthin
