70 HP Four stroke Yamaha

[blw]

Does anyone have any knowledge of a 70 HP Yamaha four stroke that has a jet pump on it ? These motors are the same displacement as the 60 HP , but running a four valve per cylinder head. They are suppose to be pretty hot, just curious what one would do with a pump on it ?
Thanks , BLW
