We just bought a beat up flat bottom boat, and we are excited! We need some help in finding out what year and mix for this Johnson 9.9. The model# is 10R75C, and the Serial# is E4183824. It states operating range 4500 to 5500 RPM's....can we get it to go faster? Ha Thanks so much! We have never owned a boat before, so forgive the naiveness!! Please help!
