I have to disagree with smokeonthewater. In a coastal application where I live an aluminum prop is a sign of a new guy. They tear up on anything, and if you hit a sandbar running a pass they can leave you without power up sh*t creek in seconds. I worked out there & it happens often.

That's why they have rubber hubs, on impact they spin loose & provide the needed give, & then it's change the prop or lose MOST of your power, but you can still keep steerage & out of trouble.

He is correct, of course, that a stainless prop is not the weak link in the drive chain like a aluminum one, the shaft, the bearings all take more stress from that weight a hard impact.

Two theory's I guess, but I'm not about to install the weak point on my drive system, I run a cupped 19 pitch Michigan wheel & have an old stainless Mercury wheel in the boat as a backup, I've had on 3 boats over 20 years, it's been trued & rehubbed once.

The only point I disagree on is where you said we disagreed.... there are definitely conditions where tearing up the drive is far less scary than being without power and you have to choose for your own situation.... Personally I boat in the river and have friends who bust props and drives fairly often... I haven't even nicked one in several years but I stay away from the eddies that attract logs and I am not at all bashful about using the trim switches in the shallows... The last one I busted it took about half of one blade and maybe a quarter of the other two and I lost I don't have to deal with treacherous inlets and I have no need for a stainless prop BUT that is just in the conditions that I operate in.
