Yamaha F90 2013

Engine will not make power. Replaced plugs, fuel line, water separator, cleaned injectors and fixed the anti syphon valve. The engine has less than 90 hours on it. Was thinking it may be the high pressure fuel pump. The engine will make ‘power’ with no load but when loaded will not get passed 3800 rpm’s. At a loss...... Any help or thoughts would be greatly appreciated!
