My oil injected 1992 Johnson Faststrike 150 on my pristine 1992 Ranger 361v smoked a lot when cold and a little when warm.....and ran perfect for 20 something years with NO engine repairs until someone wiped it out on the freeway a few years ago. I get the EPA and all but I kinda wish my 250XS smoked just a little(ya i know I can add a little oil to the gas to fix that). I truly believe these newer �cleaner EPA friendly� 2 strokes are running so lean that it shortens engine life. Part of the demise of the 2 Stroke. Oh well, somethings progress forward and somethings progress backwards...........You state your motor runs fine? Relax and be thankful. I kinda miss that early cool morning cloud of exhaust when starting out the new day in anticipation!

Johnson GT 150, shes a smoker, but fouls no plugs and after initial hard/cold start, fires up well for rest of the day.


Lets me know she's ALIVE!!!!

I am guessing that smoke is what has allowed you to get to 1000 hours on the original power head. I agree with the other reply regarding motors running too lean. There has to be an explanation for all of the boat and motors for sale with rebuilt power heads with less than 200-300 hours.

Mine three.

+4 I don't premix but it does smoke a lot especially on start up and in the cold

My '01 XR6 smokes in the mornings, just part of the deal. My Uncle owned a motorcycle shop for almost 40 years, he told me that if a 2 stroke isn't smoking, you should be worried, and lil smoke never hurt no one!
