It has been a while since I was last on park but, I can honestly say I don't think they have ever been switched on since opening, i remember the guns on the boats used to have a sweet spot where if you got it just right the water would just keep going and going until the ride ended
As well you don't even need to be a child to go on this attraction it is fantastic and fits to all ages (or so I think other peoples opinions may differ) but as a whole it is good to see that the ride is back to its former glory with the guns being back in operation, it is sort of a one way splash battle though
