Re: Coupler or Hub ?
I'd just get those props rehubbed and then keep my eyes out for a pair of used props in the size you want for spares/other set. I like having a couple of sets around, different pitchs or styles, a pair for when you really want to put the hammer down and another pair for just cruising around.
At least it's not the coupler,

What kind of Drives are you running. I got tired of prop hub damage and went to solid hub. No more let downs. With the bravo drives and not too much H.P. there will be no problem. I've hit sandbars that actually stopped the motor. I just get out push, or get towed off and start it up and all is A O.K. BTW Flow torque is Crap ! They only did that so stores could stock less props and interchange the hub for various makes. I think Merc. and Michigan love to sell more props and increase their profits. They have shown us that it is more important to make money and skimp on products and shaft thier customers. BBB

Getting new hubs pressed in is not too expensive. I have a set of Mirage three blade props on a boat that I am selling. I just checked into it and it was like $15 for each hub and $45 per prop for the labor.

Mike, solid hub is just that. In place of the rubber bushing it has steel "inserts" for lack of a better work that welds to the splined opening the slides down the propshaft. I don't think I got the terminology correct there but you get the idea. Basically, instead of rubber it's steel.
The rubber hub is designed so if the prop hits something, the rubber hull takes the shock and breaks rather than breaking either a prop blade or a gear or whatever.
The solid hub is "higher performance", no flex, but theoretically it could result in breaking something more expensive if the prop hits something.
In Florida, where there is so much sand, I really don't think it's a concern.
I remember a comparison test, oh maybe six or eight years ago, and on the same single engine boat (maybe Hot Boat????), the solid hub prop was 1.7 (radar) mph faster. I believe the boat was running in the upper 80's.
