Hi Mate,
Crisso is my "Cousin" from Oz.
Anyway the 96XP is SeaDoo Model no. 5662, it only has one motor some people refer to it as a 787 actually that's the correct displacement, some people just round it off to 800, but it's the same thing.
One other thing, while this won't effect performance, I noticed from your picture that the handle bar cover is missing, I would try to find a good used one, it's going to be a lot cheaper than a trip to the dentist.
