Title says it all, I have a 98 25hp omc carb I was wondering if it would work with my 91 johnson 25 hp. Having a backup would be nice for changing at the dock, I drive to far to fish just to turn around and go home because of a carb problem. I do everything necessary to prevent it, but just in case...

Go to shop.evinrude.com and look up both carbs. They have good diagrams.

98 they offered the 3 cylinder 25 hp. as well...look for a carb that resembles yours and compare orfice jet no's, carb kit no's, etc...do any of the 98's internal's match your 91?..marineengine.com has diagrams and part no's

Thank you gentlemen, found that the jets are different for slow and high speed, no match, appreciate the guidance
