Hello. I just picked up a 01 seadoo speedster. V6 merc. 240hp. Was running great. Took out running fine. When trying to power down I pulled the throttle all the way back... Rpms where at 4000...And when trying to pull back in neutral. I had to use a lot of force to do so...and it wanted to go forward...the rpms where at 4000.. I couldn't get it to go into neutral at all because of the high rpms.. Need help
