I have just purchased a 2006 Yamaha 2 stroke 6hp outboard and there is some confusion as to what the fuel mixture should be!
Some forums say 50-1 some 100-1.
it will run on either.
But if you let it sit for long periods between runs then the shiny internal parts can rust up without the extra oil to coat everything inside
Motor will last longer at 50:1------ as in many years.-----Totally the owners choice.------This topic usually brings much debate and proves to me that folks are not well versed on the internal workings and lubrication of a 2 stroke motor.
I also have a Evinrude 15hp that I run on 50-1 which has done so since 1988 and still runs great. So if my new Yamaha is also 50-1 I won't have to invest in another fuel tank as I can use the same one for both outboards.
