have 90hp sea doo spark with about 75 hours on it. starts up fine but not much low end torque but does kick in and goes as normal at high speed. Spark plugs need replacing? thx.
I had one other thought. Is that an ACE Engine in the Sparks? If so, make sure you're not using a Trainer Key. Also check to see you're in Sport mode and not ECO or Training. I have the ACE Engine in my Blizzard and it comes with a Training Key which is Green in color. In Training or ECO it cuts the torque in half. The key of which I'm referring is the snap on plug with the tether.
