    What I meant was there are no parts to swap either internal or external that will increase the hp of your 18 hp. The only complete powerhead swap that might work is a 1970’s 25 hp because it shares roots with your motor. Personally, I don’t care if you hot rod a 1950-60’s 18 hp. There is nothing rare or special about them. Enjoy the hobby the way you want. I’m just trying to save you some trouble and possible expense.
