Hello everyone. I have a 1999 seadoo challenger 1800 jet boat. I took it out a few weekends ago and the left engine is not putting out hardly any thrust. It sounded like the engine would go into protection mode around 6k RPMs (jumping RPMs 6k to 3k to 6k and sometimes the engine would shut off) but it would come out of it around 4k or less RPM. The impeller and seal look good. Any ideas on what could be causing this? Thanks in advance.
