Lord Stanley looked more like Lord Jet Ski on Monday ... 'cause Tampa Bay Lightning stars Alex Killorn and Nikita Kucherov just took the Stanley Cup for an epic ride on the water!!!
It all went down at the NHL team's championship parade in Tampa, Fla. ... and video from the scene is absolutely AWESOME!!!
The two put the trophy up front near the steering column ... and then took the title bling out for a joy ride.
At one point, the guys maneuvered it all the way over to a packed crowd .
