[Ranger620]

I have a question has any ever changed the isolater on 2001 fourstroke 50 hp carb to a 60hp isolater it seems to me to be the only difference between the two motors it should mean a 10 hp gain. I dont have the the Bigfoot I know that is different on that model. Anyone with any suggestions or warnings? the part number is 857104T... Isolator
