Codes.....?
A lot of the codes or faults can be read right from the ski. But the only tool Seadoo keeps from us, in doing ALL our own work is the MPEM programmer. You'll have to have a license to order one of those. I"ve seen them on ebay for as little as $1000 or just over $2100..........but I'd be skeptical of buying one, since you have to have a password to use it. I'd be afraid that it was stolen or the password missing..........so, I don't have one.
But a ski your age, you shouldn't really need it.........:cheers:
