/o/ why has no one swapped a jet ski engine into a motorbike/small

Powering a waterjet is a lot different than being directly connected to a transmission/wheels/etc

how so...
what makes this so hard, so stupid, that NOT ONE person has done it?

You could do it, for the 30 seconds until the engine failed.

"This Japanese jet ski is propelled by a supercharged and intercooled 1,498cc, liquid-cooled inline four-cylinder engine that cranks out an impressive power of 300 hp. "

or a 1000cc 2 stroke thats supercharged...

Because they're shitty engines. People put bike engines into jet skis for a reason. Hell someone even put a 13b into a jet ski.

There's a racing class for a snowmobile engine in an open wheel car, is that close enough?

what makes them this bad?

They're designed to power waterjets.

Marine engines are cooled by the water the vehicle is in. The small stream you see shooting upwards behind watercraft is the water pump discharge. People do swap big bore 2 strokes out of snowmobiles as they have a somewhat conventional cooling system that can be modified for summer use. Also snowmobile drive systems are cvt so you don't need a transmission, just the 2 clutches from the sled, a jackshaft and chain drive.

Yeah, that's a four stroke engine you're looking at numb nuts.
Infact, the Kawasaki range of personal water craft use a supercharged version of the ZX-14 engine.
Two stroke jetski engines are typically ~800cc twin cylinders with no forced induction.

Not sure if you're taking into account marine engines usually (as in the case of jet skis) have their own sealed liquid cooling system. The water it's running in only runs through a heat exchanger, not the engine itself.

This. The load requirements are hugely different.
