elevation and carb settings for 720's

[seadoobie]

So I recently moved to Colorado and wanted to know what I would need to do to my carbs before running them at a higher elevation? I am at around 6000-7000 ft now. Its a lil eirly in the season still, but if i need to work on it now, it would be the time for me. Any advice or help is appreciated!

I wouldn't instantly try to re-jet the carbs. Since you have less air, you will make less power. Seadoo's "high Altitude" kit is actually an impeller with about 1 degree less pitch. This allows the engine to rev up a little better, and gets your top speed back up. Also... since you have less air to compress... raising the compression will give you a big gain. The only draw back is if you do that... you may need high octane fuel if you go back down to sea level.
