    Sure you could...but pulling the boat hauling the tank would be a bitch!

    I service and repair LPG engines every day. Don't do it. You lose half your power and gain 90% reduced reliability.

    Liquid fuel just needs one simple pressure regulator or less. Gaseous fuels need two, and a vaporizer. And those two little regulators are flimsy thin rubber sheet with a weak little spring. It doesn't take much to mess them up. Throttle response is a nightmare.

    If you think the guys with corny homebuilt turbo setups have bad reliability and are always wrenching, wait to you see a NG, PG, or LPG engine.

    all the pounding I'd worried about getting a stress fracture in the gas tank, remember the said gas tank would be between your legs. Not to mention the danger of having a gas leak in the confined space of a jet ski engine compartment. LPG can offer some good performance gains as it can handle high compression , especially with forced induction, but the engine needs to be built specifically for it. With LPG on a stock engine, and as Buliwyf said, performance will go down
