Engine size?

[jmrochelle]

Hi All, I just became the owner of a 1997 seadoo speedster with twin rotax's. How do I find out what size the engines are? Also what can I do to get better hole shots. Or should I ask what size skat trak impellers do I need?

Thanks
Jody

I'm actually hopeing for the same answer... I've got a 98 Challenger with twin rotax 787's, but I was told they were the 90hp model. I haven't found a single other post or anything to make that seem right. I'm assuming they're the 110hp motors. Is that right? Is there a way to tell the difference? If it's speed, well, then I'm able to hit about 48 with 3 people on board, which seems pretty good compared to other posts on here...
