Marina Mafia jumps in for the risky ride up Niagara river to the level 5 rapids, making your way up river past the hydro dams past the BIG rapid and finally to the whirl pool. You will see man go underwater with the Seadoo and also another flip over off his Seadoo in the rapids. Making your way to the whirlpool seems to be as far as anyone is allowed to go, but I don't know if we would dare further if allowed anyways.
