Hahaha! I just reread the entire thing and couldn't believe i left myself hanging!

I was like "what the f, self?"

YT - long story short I kept the 3 blade aluminum that Cobalt recommended. The 4-blade was good but I can't explain it, just didn't feel right. My brother thinks I'm crazy but I notice different things than he did. he says it vibrates more with the 3 (even though it's unnoticeable to anyone else when trimmed properly) in the mid range. It turns better with the 3. The wake is better with the 3 - don't know how to explain what I mean by saying that.

The hole shot was not noticeably different with either. The kicker - the 4 was a little bit faster. consistently 49 on gps is slight chop with two guys and a half a tank. 3 was 47 - 48 on a different day with same conditions.

Double kicker - I couldn't get to 4800 RPM with either. 4300 ish on both. I was perplexed a little bit and ran out of time last summer so i went the path of least resistance and stayed with the prop Cobalt recommended. Then I had a baby. I still want a prop but I want a prop that someone has used successfully on my set up. Enter Fozzy. Time to Frankenstein this thread in the 190 section.

Also the 4 blade was a little wonky for docking.

How do you tell what pitch prop you have? I don't think mine is stock beings it's stainless.Is it stamped somewhere?

Yes it's normally stamped on the barrel of the prop or on the end of it where the nut goes. Not YT either a nut that holds the prop on.pictures if you find them we'll help you once you find them.

If you can find a part number stamped somewhere that would work to look it up too.

That's why I suggested the Alpha 3 drive.
