Hey guys having a issue with my 12f. My ski is in slo mode I noticed it last week out on the lake and held mode and switched it to fpo worked fine. Took it out sat and was still in fpo working fine. when I got home and was putting it away the buzzer went off held a constant tone and shut off with the display. Took it out on sunday it was back to slo mode and I cant get it back to fpo because display is not working. But on the way back to dock I jumping some wakes then stopped and idled for a minute when I started going again it had full power again It stayed in full power for maybe 10 min then slowed when I did a doughnut. Any ideas is it the display? New gas and plugs spark all cyl compression good thanks
