we have a 1996 40hp 2 stroke.
normaly we found most to be 50-1 mix.
but this has a sticker saying 100-1 on it.

just trying to find out what mix goes in.
thanks again
 
"Not sure where the sticker ca

"Not sure where the sticker came from - the service manuals covering all the 40 horse models during that period call for 50:1

Yamaha was the only mfg successful at producing a 100:1 outboard and even though they build or provided parts for many of the Merc models, there was not a Merc model rated for 100:1 - at least one that you pre-mixed.

OMC also had a couple years of 100:1 motors in the late 80's - they found it to be a problem and issued a statement, that could well apply to any motor (aside from the Yami's so designated).

You can decide for yourself, personally, I would be running 50:1 if you use the motor for anything more than trolling...
