I haven't used my 04 Launch ssv since late June. Took it out this morning and it won't shift into gear. The throttle lever will not release from the neutral position. I can push the neutral button to keep it out of gear and throttle it up, but the lever will not move out of neutral otherwise. I felt around behind the panel and I can't find anything that appears loose or broken. Any help would be appreciated?

Thanks,
Trent
