Repowering pontoon

[Prostar2009]

Have a 2004 Yamaha 25 Hp 4 stroke and would like to up grade to 90 hp Yamaha. One dealer told me my controls will not work another dealer said the would. Not sure who to believe

posting the motors and the control model & IDs might help people to know what you are dealing with

and what 90 are you trying to go to?

Some motors have push to open and some are pull to open throttle.
some con*****ers can be switched around to do either.
some motors could have electronic controls
