Got these two sea doos and the GTX needed a new mpem which the old owner supplied me with, how can I fix the dess key problem. Also what would be a good price to pay someone to help me from sitting for 2 years they need a small tune up, I'm in San Antonio Texas and don't wanna pay high dollar at a power sports shop ??? Please any advice will help the GTX has the acceleration stuck so I think it's gonna need a new wire
