The application chart goes by size and cca (cold cranking amp).
Get a 12V battery that physically fits and turns the ski over continuously for a few minutes before dying.

(sorrry to jack thread)
I've had very good experiences with the Jetworks XC35B battery.
Some online Jetski retailers sell them, HotProducts does, and of course, www.jetworks.net does.
me too... amazing battery.
