I have a 25 Cobia center console and it is rigged with a single 225 Yamaha, the prop was in bad shape so I had it worked on and when it was done they said it was changed from a 16 pitch to a 17 but it needs to be 19? What is the correct prop size and pitch for a set up like mine? Does anyone know what the RPM operating range is for a boat/motor combo like mine? It cruises around 25 knots at about 4500 rpm is that around where it should be (1/3 tank of fuel and 2 people)?
