Top speed reach 61 mph only
yesterday I made a test for my ultra and on the gps I reach only 61 mph I feel it,s low isn;t it? I had half talk and the sea condition was rough and bit wavy my speedo meter is giving me wrong reading from day one I onw this ski the dealer tried to fix it but still not fixed reading randomlly..so guys what is the top speed for stock ultra 250? and what could be wrong with the speedo meter..today the weather is much better I will run onother test and if it still the same speed I should do something...I like the acceleration and not much considering top speed but still wana it to run normal average ultra speed

Forget the skis speedo.It will always show shit.
Normal speed for stock ultra is 64-65mph.
What rpm's are you turning?
Check the engine oil level and study

How rough was the water? If your real rough, then take the 61 and run! If its flat as hell, and your doing 61, then sure, you have an issue. Check your max RPM. Press the mode button severl times, you can see the max rpm is you depress it enough times.

I had the same problem when i first got my ultra. Check the oil level. Mine
came overfilled with about 1.5 extra litres. Also make sure your blowoff
valve is not leaking, your rpms should be over 7500.
Also do not rely on your speedometer, it is very innacurate. Do the speed testing with a gps system.

What was the air temp?
This ski hates warm air and humidity.
Your RPM should be around 7500+.
Find another stock ultra in your area and do some side to side test runs.
