I think the following cases help you:

1. Exposure of the waterjet inlet to the free air

2. Flow separation in front of and inside the

inlet

Jamal Alizadeh

another cases can help you are :

1.Cavitation inside the inlet

2. Ventilation and penetration of air from

the free surface or from

entrained air in the boundary layer

Yasser M. Ahmed

I think the main reason for the causes of engine load fluctuations in case of water jet system refer to the fluctuation of thrust that is produced by the system impeller. This may occur due to the cavitation inside the system especially at high speeds.
