I have a 1993 and a 1991 superjet. The 1993 has an ocean pro nozzle and rideplate. The 1991 is stock.

If I look at the pumps, they look different. Did yamaha use different pump styles between 1991 1993?

The 91 has a downward facing pipe to the left of the pump, the 1993 doesn't have that at all. I'm just trying to make sure that both pumps are stock.
