when I bought the boat and motor it had a alum. prop 21 pitch 3 blade, I ran it for the first year I owned the boat and had to put a dol-fin on it to lower the bow. by the next spring and alot of talking and research I bought a 19 pitch 4 blade S.S. Trophy. after playing with the exauhst(sp?) ports I got it to throw the boat up outta the hole at full throttle then as the bow lowers throttle back to 3/4 for my power trim work, once trimed out go full bore if the water is calm enough, that'll get me up to about 45 M.P.H. otherwise in rougher water I tend to keep it at 30- 35 M.P.H. BUT I had to take the dol-fin off with the 4 blade. It created too much turbulance and made the bow hop.

Thanks for input S&S! I have an alum prop 10' X 13(pitch) on my 25 2 cyl Johnson. It came from factory with it & so far I have replaced with same having good thrust etc. with my 16' jon & hope same with my Lund 16' SSV Wilderness. Dealer thinks it will do what i need. I have stayed with alum vs ss due to tuff rock structures i fish below conowingo hydro plant etc. Alum seen to handle hits better & affording a lil more protection to lower unit. If i fished 100% sw & non-rocky areas would definitely go ss. MY Prop (oem 175191):

Over 15 years a 3 boats from 19 to 31 feet, I've had both. Offshore stainless is the ticket. Back-bay, river, etc...stainless is durable but I'd rather chance a $100 prop than a new lower unit if the hub doesn't do exactly what it's supposed to. Any high speed impact with a bar will do a number on aluminum but the gear case should be OK. I hit a dolphin, yes, a dolphin in Delaware Bay while I was moving about 30 mph. The port side Merc 225 EFI kicked up and then all seemed OK. Two trips later the lower unit failed. The rebuilt replacement cost a bit less than 1500 and the $300 stainless prop was undamaged.

You can look at it two ways. Stainless you will get your best performance out of the bout because they don't flex like aluminum. If you are mainly boating in lakes or where there arn't alot of rocks I would defintly go stainless. If you fish the rivers and where there are alot of rocks I would stick to aluminum with some gards. The reseason I say this is because it is alot cheaper to replace and aluminum prop than it is to replace a gear drive! Stainless only gives the amount your rubber hub will allow it and alot of times that isn't enough.

Saw it flopping on the surface about 75 to 100 yards back when I turned to determine what I struck. Went back and looked but found nothing and felt bad about the whole situation.
