Looking some help or insight, I have a 2010 f115 with 350 hrs on it and in the last year my wot has slowed down by 800 rpm. Boat would run 5900 rpm and now maxes out at 5100, I have carried it to a shop, they did annual service , replaced timing belt and idler pulley, send injectors to be cleaned, these made no difference in the wot, took it back and they replaced the high pressure fuel pump, still made no change to the wot. I have mechanical knowledge but am not an outboard mechanic looking help before I spend another $2500 with no change in my boat. Thanks
