[QUOTE="Stefan, post: 327765, member: 7352"] Hi Shawnfish, Check out this link here to BRP for Johnson 1989, 20 HP and 25 HP models. 20 HP Carb is part # 0433193 (this is what is etched on the carb on my 20 HP as well) 25 HP Carb is part # 0432704 So the carbs are definitely different part #'s, but from all the research I have done the only difference between the two engines is that key hole restrictor plate on the intake manifold of the 20 HP... Perhaps the carbs are exactly the same, but were just cataloged in their inventory differently as seperate part #'s for sorting purposes??? Or perhaps they just assign the 25 HP a different part #, so it seems like it is a different part and they can charge more $$$ for it? Or maybe I am completely wrong, you could be right and they are different carbs all together? Either way, the results speak for themselves: when I bored out that key hole on the intake to match the carb perfectly, air flow increased, speed increased, the boat planed, the engine idles better and I'm still smiling. More air resulted in more power... [/QUOTE]
