Prop Question

[chumbucket]

I never experienced any lift with the four bladed prop. But, it was a very heavy boat. You may be correct. I just wouldn't be able to say one way or the other.
For my use, I like a three bladed prop best.
The other question I would have is; Do they make them in aluminum? Most of the ones I've seen are either stainless or composite. Stainless is good, but expensive. Composite is cheap, but flexes too much. Believe it or not, aluminum will flex under load too but is a good compromise in material and strength. With stainless, if you're not careful and golf it off a rock, you risk breaking gears in your lower unit. Composite will snap (better have a spare). Aluminum will ding and still get ya home in most cases. Always a good idea to have a spare onboard no matter what even if it's not the best shape.
I know it's a lot to consider. Many people never think twice about the prop they put on their boats.
