If it DC, no. If AC, there is a big difference between 50 cycles per second and 27 million cycles per second, so probably no. An unsuppressed DC motor might give problems at the kind of power needed to chuck enough water high and fast enough. I would be more worried about the effect of water falling on my boat than any interference coming off the wiring.
As Dougal99 says, once they get the bill for the power needed, it might not run that often anyway. Once you allow for conversion inefficiencies, you get about 1 horse power per kilowatt. One HP will move 550 pounds one foot upwards in 1 second. To get a noticeable amount of water high enough into the air at any one time takes quite a bit of power.
