Author	Topic:   1981 Johnson 35 Restrictor Plate Removal; Carburetor Change
skred	posted 10-10-2013 11:14 AM ET (US)         Does my 1981 Johnson 35 2 cylinder simply have a carburetor or restrictor plate setup that could be changed to increase the horsepower?

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...

Propping and set up are 90% of the battle. I just upgraded to SS prop for my 30hp and it is great. Great reading. http://www.boatracingfacts.com/forums/showthread.php?15576-Evinrude-31-8ci-Mod-Advice
LakeArrowEd	posted 04-05-2014 10:51 PM ET (US)          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.
