For the purposes of searching articles on the forum, I have started a new thread on the 3 blade to 4 blade propeller change on my 2004 Dauntless 180.

The OEM prop was a MiragePlus 3 blade, 17 pitch. It performed fine and at WOT generated 5600 rpm at 40 mph.

I wanted a spare prop and read a lot of good things about going to a four blade. After much research, I decided on the Mercury four blade Vensura 17P. This was the same pitch as the three blade.

Out of the hole is much improved with near instant results.
Mid & Top End Range was effected by 1 to 2 mph at most.
Stability in rough was remarkably better.
Handling in tight turns is also better with the four blade.
WOT rpm is the same.
