Mercury sport jet 90

[Josh122593]

I currently have a mercury sport jet 90 on a 93 bayliner jazz 1400.I would like more power and im only 14 so i dont know much about the jet pump,mostly i know about the motor, but i was wondering could you put a sport jet 120 or 175 on the 90 jet pump.

Well I don't see any part numbers that match up on what you have sport 120 looks it came out in 96 and yours is a 93. With the jets everything is matched up to get most out of the motor, there just not a lot you can change. Impellers are not the same nozzles are not the same size. I just don't see it happening.
There may be more out there that can tell you more. I don't see a lot of these
in my shop.
