Re: Mercury outboard prop upgrade?
We would need more info from the stickys at the top of the prop forum
You wouldn't normally change the number of blades to increase speed for every day operation.
If you have an original 2 blade from the factory most modern 3 blades will out perform it.
Very basically a 2 blade is supposed to be ideal for speed but are otherwise limited for performance.
A 3 blade will do better all around over a 2 blade of similar construction.
The 3 blade will likely push a load better get out of the hole faster,stay on plane better at reduced throttle
And probably have a little better slow speed control.
Todays state of the art al props have an edge over older props.
Props using the Squeeze casting technology have good performance.
