Does anyone know what the Max RPM range should be on my 2008 F225TLR 4 stroke. I dont feel something is right. Im only getting 60mph fully loaded with 2 people and thats with it turning 6100rpm's. Im worried im pushing it too hard but this is my first 4 stroke. Is that all the top end i should be seeing out of this motor. Boat is a 2009 ZX225 Skeeter.
