Couple events needed.

[Green Link]

These events need to be made:

Ifplayerenterswater - A variable event.
Vehicledisabled - Makes the vehicle so that it doesn't work until enabled again.

[Ad Bot]

[Exo Pheratype]

These events need to be made:

Ifplayerenterswater - Made already by trader

Vehicledisabled - I think that would be possible with onvehicletouch but it got failed :y

[Green Link]

If player enters water: First off it is for the VARIABLE EVENTS. Secondly I mean any type of water, not just the water brick.
