I have a 2005 seadoo utopia 205 240 hp merc.m2 efi. I bought this boat new in 2005.Here is the problem.This year i lost 10mph ,the boat usually at full throttle runs at 6000rpm,now it runs at 5500 and top speed is around 40mph,all fuel filters were changed and new spark plugs ,every once in a while the boat would race up and act normal but then go back to low rpms,from 3/4 throttle to full no difference, it feels like a injector is plugged and it clears once in awhile.no competent mechanics in area . Dealer is useless.Heeeeelp
