3 1/2 blade prop for sale
 

What do you think. Prop only had about 6 hours on it.
I am fully surfacing it. Prop shaft is 2 inch above hull.
Looks to me like I hit something.
I don't see any signs of fatigue on the other blades.

This prop was 5 MPH faster than the stock 28 Bravo prop that I used as a spare.
Would you believe I hit 100 MPH with it this way.
Noticed a LOT of what felt like wave vibrations but new that I shouldn't at that speed.
Slowed down and the vibration got worse.
Put the boat back on the trailer and found this.
Changed to my spare and could only hit 105 where I was at 110 with almost full tanks earlier.

Bravo props are not strong enough to be full surfacing, especially with the HP you have.

Agree. You care going to need a Herring or similar, or these other cast props are going to make this a regular occurrence; and you could tear up other stuff. I had a prop blade tear away for no reason and it sliced up the entire lower when it came apart. You need something stronger so it doesn't come apart and end up causing a catastrophe either.

Just grind the other 3 down to match. It's not that bad...
