    Powerhead swap?

    Idle thought here because:
    1) Who doesn't want more power?
    2) It would be cool if possible

    2002 90 hp Merc 4S ELPT 0T562954
    Would it be possible/practical to swap a rebuilt 115 powerhead of the same year onto this engine? What are the differences? Would the existing carbs/fuel system bolt right on? Gearing issues?

    Really not feasible as the 115 is an EFI engine.
