fuel mixture

Does anyone know the fuel mixture for a 1980 25 horse evinrude boat motor, my guess is 50;1 but not sure?

Re: fuel mixture

You would be correct 50:1 is the right mixture make sure the oil you are using has TC-W3 marked somewhere on the label.

Re: fuel mixture

50/1 is correct.

Re: fuel mixture

Is the same ratio applied to a 1983 60hp evinrude motor? I currently have my dads boat at college and he would kill me if anything happened to it. Lets use an example so i can be clear..say i put 5 gallons of gas in the tank..how much oil?

he lost his sheet we had that broke it dwn gallon for gallon. THANKS!!

Re: fuel mixture

yes any motor made after 1970 can run 50:1 so here print this out so you can keep it on the boat

kuch its simple ( well sort of some people find this too hard) a gallon is 128 oz right? now divide that by 50 youll get about 2.6 convert that to ounces. now for your theoretical 5 gallons youll mutiply 5 by 2.6oz so youll come up with 13 oz of oil but we here like to round that up to one pint but truely you can do six gallons of gas with one pint of oil (16oz) thats 50 :1 mix almost exactly .4 oz extra oil that really wont make a difference and when in doubt add a little extra and keep a set of spark plugs on the boat with a wrench (i think youll need a 13/16" combination open end box end wrench )keeping 2 plugs and an apropriate wrench will save you ALOT of face with your bro's and hoes when your out on the lake and your engine starts acting up id also grab and extra coil pack and keep the tools to put it on and take it off on the boat (stuff happens and you want to impress the chicks right?)

make sure you use TCW-3 oil not air cooled engine oil i like super tech from walmart or penzoil (also from walmart 12 bux a gallon if you catch it right)
