New member here and have a question about a 1986 Evinrude 28 spl. The lower unit is the non thru hub exhaust. I picked up a johnson 25 parts motor with thru hub exhaust. Is it possible to modify the Evinrude to carry the thru hub exhaust from the johnson? I'm looking for better performance. Thanks!
 
Yeah, what pappy said.

The lower units won’t bolt up. The thru hub will get you a better more efficient propeller, but short of better reverse you likely won’t see much performance gains.

Power head swap to the thru hub lower and the 35 ho intake and carb swap would then be an option.

Having said that you have to figure out what carb that motor has as is.

The “Specials” were a mish mash of components geared towards making a cheap commercial motor.
