2011 GTX 215. I think I sucked up some seaweed or something in the back bay. I rode for a bit towing a tube when I lost speed and sort of went into limp mode I think. I couldn't get any speed up even though RPM were revving up high. I had not engine lights or indicators suggesting a problem. I made it inland and went in reverse a few times to maybe blow any debris out. I should have checked the intake grate first though. I took it back out after a bit and it seemed ok. I replaced the spark plugs bc I thought it was still sluggish. Question 1 is my ski doesn't seem to really pick up any mph until RPMs are up. It takes up to 3500-4000 to get going. I would say I get to around 45 mph at 5000-6000 Rpm. Is that normal? I am used to my other ski which was muck lighter and smaller and was very quick from the Jump - a Yamaha EX. I was looking for a chart that may show RPM and MPH and what they should be. Does anyone know if that exists? I have not tried to go all out to record the RPM vs top speed, also wear ring and impeller was replaced by PO a year ago. Any insight would be appreciated.
