Ideas please... Bought the 2012 Seadoo 155 new. Ran great last year. At 25 hours the maint. required light appeared - knew this was for the oil change. Parked for the winter at 26 hours and did the complete oil change. Took it out this summer, no problems - runs great. At 27 hours, the maint. required message reappeared. Its somewhat sporadic. The machine did get flipped at 28 hours, but we cleared it out and had no issues. Now has 30 hours, running great, but the maintenance required message keeps appearing. Seems to appear less when its been running for a bit. Any ideas?
