Yep! But honestly if you haven't spent any time on a wave runner I'd consider renting one first. I found them to be fun, but only for a couple of hours then I found myself really bored trying to figure out what to do next.
Just like anything else though make certain it's seaworthy and runs good, the two strokers are dead simple of course but the four strokes are well.... Four strokes, and if it's been abused the impeller can be pretty chewed up.
If you have friends with wave runners though, it can be a lot of fun out there rough housing in the surf.
