i had a 120 on my Mitchell, ran great, but I had one problem with it that I could never figure out, had the same problem on a freinds 120 also. At idle, I could never get it to hit even on all four, you could pull the plug wires and the cylinders would drop different amounts, # 4 wouldn't even make hardly any difference, went thru the carbs numerous times, set the linkages per the manual, double and triple checked the linkage and settings, then went back and set the linkage so it would idle, ended up taking the idle speed knob all the way out to set the idle timing up enough so it would idle in gear. I checked the reeds, OK,made sure no one had mixed up the airbleeds and jets, spark and compresion were ok. Thought it was just mine, till my buddies did the same thing, even swap carbs from another motor and it made no difference. I never did get in to changing idle jet sizes(did'nt have enough to go experimenting). Got it to run good enough, but was never completely satisfied with it at idle.

My 140 idled like CRAP until I rejetted it. Mine was due to premixing, it would go to ROLLING blue smoke after about 30 seconds of idling. And it would starve for fuel in the mid range and stall out about 1/2 the time trying to get on plane. A little re-jetting and now I can idle for an hour with minimal trouble, and it will get right on plane with no hesitation either. Mine was a REAL basket case when I got it, and for the longest time I HATED THIS DAMN ENGINE! Then I decided I was going to beat it into submission and win. Now I LOVE IT!

I'll be the devils advocate and say keep the 200 and swap out the carbs for a set off a 225.

My 225 looper gets the Sea Ox right up and go!! Nice motor in deed! I am very happy with how the boat went it all the test runs!! Toped out at 35 mph, But I might be able to do better once I get use to the trim tabs and stuff?? The Ox is a heavy boat!! 3000K just for the hull.
But no matter thats fast enough for me! And with the price of gas I will be going a bit slower this year!!
