So I recently purchased my 2017 Sea-Doo Spark 3up, when I ride alone the ski performs great, however when I have another adult as a passenger, the ski struggles. With two adults the front end lifts unusually high during acceleration, and I need to get it to a certain speed to even it out, ~20 mph. Also with two adults on the ski it becomes extremely difficult to steer the ski, the best way i can describe it is every time you adjust the handlebars during operation it feels like over-correcting. I am assuming that the weight of two adults was the cause for this, however the max weight capacity on the ski is 450 lbs, and I am sure we didn't reach that with the two adults that were on the ski. Is it possible that the ski is still breaking in, I only have 3 hours on it? Also I live in Colorado, therefore I have some power loss due to altitude. Thank you in advance for any replies!
