    Wondering why they have the sponsons in there? Is it for a speed upgrade? or just an overall handling upgrade? Extra money for them?

    Jerry, can you give us your results from testing ? For example, it would be nice if each piece was tested separately with the SCOM on.

    74 mph @ 7800 RPM. That's really good speed at a very safe RPM. I am guessing this is still a 91 octane Ski.

    Sambo: These Sponsoons would be an upgrade for the Closed Course guys. And potentially for the Offshore guys too; the Sponsoons are adjustable and can be set in the "up" position for less drag. JB
