Re: merc 3 blade cleaver broke
With mine, I thought the engine had laid down. There was a strange but faint vibration. I pulled the throttle back and it went away. I added throttle and it got worse. I pulled off plane and put it into neutral. Engine was running fine. Put it in gear and it felt fine. Went to plane off and the whole back of the boat was jumping around. Shut it down and found the blade was gone.

HotDuck,
I remember that prop of yours. If there is some type of a casting flaw it will generally show itself quickly. In your case it tool less than an hour of run time. I hope the new one has lasted longer than that.
Twin engine boats are much tougher on props than singles. There are many factors that determine the longevity of the props. The thing to remember is that props flex, and like any metal they eventually fatigue and fail.

yikes, wouldnt want to be to near that when it let go.
TizBad lost a prop/shaft on one of his #3's last year on tha cat. it was a 17x31 4 blabe cleaver. that sucker took to the air for a while i heard. now that would leave a substantial skid mark if it hit anything.

Did you run over any Manatee's by chance. Maybe its stuck in one of their heads.
Can you imagine the press the Save the Manatee Club would get if they had a pic of that!

Re: merc 3 blade cleaver broke
Dont personnaly have any experience with the lab vs. non lab props. In fact, I didnt realize that the blades would sheer off on their own without even hitting an object. I would think that a non lab prop would be a little stronger cause the metal is thicker. Thats also what cuts into the performance. One prop that I thought was pretty cool is the composite one made by Piranah. You can take the busted blades off the center hub and put new ones in. The only problem, its a plastic/composite and will not give high performance. But the concept is cool.
