Jumpstart PWC?

[feb]

Does anyone know if its possible (read safe) to jumpstart a 2012 Yamaha PWC using one of the newer handheld battery packs like the Micro-Start XP3

It should be fine but I would only leave it connected long enough to get it started then disconnect it right away. I would also give up if the jet ski didn't start in the first 30 seconds.
