I just inherited a tracker bass boat from my brother with a Johnson 28SPL Model # J28ESLCCR. On the back of the engine cover it has part of a sticker that reads somthing about restricted to 20HP. Can any one give me some info on this motor.If it only produces 20HP can I modify it to produce 28. Thanks

Re: Johnson 28SPL

In all likelyhood ,this engine has been operated on a body of water that would only allow engines 20 horse or below and has been modified to meet that criteria.Those modifications can be made alot of different ways ,but most commonly are done by not allowing you to acheive wide open throttle.Look at the shifter side of the carb and you will see a little roll pin on the shaft that rotates the carb butterfly.At wide open this roll pin should be straight up and down.
