Can anyone tell me roughly what the top speed should be on one of these? Took mine out for the first time yesterday and couldnt get about 38 mph. I was reading the specs on my GP760 and seen a top speed of around 55-58, so i was expecting far more than 38 mph out of the 800.

The stock ski topped out around 54 mph at 7200 rpms. Check the compression.
