F40LA -Advertising claim said it is incredibly smooth. I got the optional electric troll controll that lets you adjust trolling speed from 650-900 rpm in 50 rpm increments. Upon start up at 750-800 rpm's it shakes a lot. Using troll control 2 settings are fairly smooth, 650,700. At 1000 it is the smoothest. Installed a prop brake to troll at 900-1000. I spent $800. for the troll contrll option which is useless above 900. Yamaha should retract their advertising claim of INCREDIBLY SMOOTH.
@rrusso421 check your valve clearances on the head of the engine...if they are incorrect that causes rough idle, my 4 stroke 15 hp yamaha idles perfectly with minimal vibration...i troll for hours with it just in gear on idle and runs fine....
@NorwegianCrows evinrude etec is a great motor...i have a 15 hp yamaha 4 stroke kicker and it idles perfectly and very smooth...i use it as a kicker for my boat
the Honda is better, i ran both at 2 different resorts, the Honda sound is so much better and you can't smell the exhaust at all.

I like how quiet it is compared to the two strokes. Thanks for sharing.

New two strokes are just as quiet as four strokes, and even more fuel efficient.
