1999 Seadoo GTX RFI - in water RPM limited??
My 1999 Seadoo GTX RFI (787) has run great all summer. A few weeks ago it would only hit 3200 RPM at full throttle in the water. Take it out of the water and it hits 6000+ RPM no problem. Put it back in the water and it will throttle up to 3200 RPM and hold. I have pulled the rear RAVE and cleaned it. The sliding valve was coated with thick black oily sludge. I have also pulled the pipes to the RAVEs and cleaned them out. I also pulled the check valve that goes to the crank case and cleaned it - I am not sure if it was stuck when I pulled it (did not check) - but it works fine now. I was also instructed to pull the front RAVE and clean it too. My question is two parts: if the rear RAVE was coated what are the chances the front RAVE is coated? And second (and most important) is that it appears I will need to remove the exhaust manifold in order to get the front RAVE out. Is that a hard task? I have the 1991 Shop Manual and it looks tough to me. Thanks for any ideas or thoughts.
