In Mario 63 how do you use the water powered jet?

In Mario 63, to use the water-powered jet, you first need to find it in the game. Once you have access to the jet, simply approach it and press the designated action button to activate it. While using the jet, you can direct Mario's movement by tilting the control stick or using the directional keys to navigate through the water. Keep an eye on your water supply, as it will deplete over time, requiring you to refill it by moving through water sources.
