Only now when they lose one, it hurts a little more. They aren't as tough as some some like to make them out to be. The 44 boat has the ears tips off the ears off two so far. There is NOHING different about a Grose prop than a Radiance or Menkins except how the blade shaped. When you can explain how the you shape the blade increases the strength, you get back to me with that info. Its still 2 ears welded to a fucking hub and sent out for heat treat. How the CNC makes them stronger I would like to hear, Genius

Rankin and Darrin take them one step further when they get them from Grose, but I am not all that sold that it helps any.

Grose props don't have welded ears. They are from a forging. Maybe I'm missing something but that's straight from Joey and Ron grose's mouth. I spent a week down there with Scarlata and saw the box of forgings.

i know and bob did not mention marine machine i was the first to comment on it, i know you didn't recommend anyone why would you you can make it yourself..and if you remember i researched the company and asked for your opinion. you said you would use them and that was good enough for me, what bob said is that a supplier has a batch of bad shafts , never who not a name out of his mouth till today, if giving him the credit for it makes him happy than he did all my research for me contacted them look at the certs and the type of machines and gave his word that , thats who to use than he did, just like with the Grose forged props he said there welded ears than there welded ears no matter what picture is posted..

So if the tip if the ears of the Grose props snap off, it proves the forging are better than welded ears? How it how the root at the hub helping the tip of the blade.

I have nothing against Grose props. I have no doubt it a great product. But the prop under my GN won 5 championships that I know of in the history I was able to track, and it was made in 1988 and final obtained a small crack in Nov 2012. That's not a bad run under a blown GN.
I paid 150.00 unseen off E bay, What does a Grose prop cost, and might fail after 2 weekends??

I don't care if its carved by hand with a hacksaw and file, if it only lasts 2 weekends, I try something else.

I the forging is a stronger root/hub, how does that help the rest of the blade. Are you suggesting the forging is stronger everywhere else over milled plate. Are does the ONLY thing it eliminates is the weld?

Sorry but GN7 is WRONG on the welded ear portion about Grose props! Forged one piece props are far stronger than a prop that has welded ears. I'm not saying a Grose prop has never cracked, but it's proven to be stronger than the standard Radiance or menkins.

Mark i know the difference lol , and a one piece prop shouldn't throw the blades off now the tip of the blade is different , but the blade coming off the hub should not be a issue ...

If it throws the whole blade or part of the blade, it is just as bad and could have exactly the same effect. Many conventionally manufactured props have gone years and years without throwing blades or parts of the blade, So to say something is stronger because it is perceived that it is impossible for it to throw the whole blade, is a bit pointless if there are reports of these props throwing parts of the blade.

in agreement i guess the reason the problems are becoming more and more is ... my reason is the boats are making more power , being driven harder in rougher water..i have not heard of a forged prop throwing a ear
