I have a 2014 GBR 2550 with a 250 HP Yamaha. My top speed is only 36mph lately, I don't run at full speed often so I don't know how long this has been going on but recall my top speeds were ~ 45mph when I first bought the boat. Does anyone have ideas on what to look at or can anyone with a similar setup share your top speeds. Boat only has 200 hours, runs well otherwise and the pontoons are free of water...
