:dunno:I have a 04 F-12x and it runs great. I purchased it last yr with 100 hrs on it for 4,000. I never had a 4 stroke so this is all new to me. I have a top speed of about 66mph. My problem is I cant get out of the hole. When I nail it out of the whole I get a stutter. (sounds like a air pocket) soon I get it up on plain it takes off like a rocket. Is there a ride plate that I can put on to help me out of the hole?
