In several brands of props they have different diameters........we all know and understand to a certain degree what pitch and rake does and the effect it has on a boat.

If you where given a certain prop.......say brand X.........now mind you I am just throwing numbers out there for conversation sakes.......say a 13 inch diameter prop versus a 13 1/2 inch prop.....exact same prop, pitch and brand. What will this do to your engine......what are the advantages or disadvantages???
