Does my 1981 Johnson 35 2 cylinder simply have a carburetor or restrictor plate setup that could be changed to increase the horsepower?

That is the max HP for that block. 35hp out of 31.8 cubic inches is great. They built a 20hp, 25hp, 30hp and 35hp on that engine block.

Thanks for the info. I suspected that. It seems to an excellent choice at about 120 lbs on my Sport 13, Since the 40 is a heavier model, the weight difference would seem to make the performance almost equal, but with the economy being better on the 35...

If you are handy and have free time, I am sure you can squeeze more speed and power out of it but it is indepth.
Propping and set up are 90% of the battle. I just upgraded to SS prop for my 30hp and it is great.

These are great little motors. I have a 1983 Johnson 35 ELCTS on the back of my '77 13'4 center steering sport and it scoots. I was thinking about repowering because I'm currently customizing the hull into a Super Sport with a right hand steering console and had some weight concerns but the heck with that. I'll reprop this little motor if it needs it and be on my merry way.
