Bronze vs SS prop?

[76BARRON]

Ron , My dad's boat is an old 65 Stevens flatbottom with a 427 ford and has a 3-blade 12-16 bronze prop and so far he like's it fine. My feeling is that in the past 40+ yr's that prop technolegy may have improved since then?
I am thinking that some of the new 3-blade SS props of the same spec should offer more? thinner blade's, more rigid and just over all better performance. What do you think? Is it worth the $$$ to get another prop?
Sometime soon i'll pull it off and have you or Chad check(spec) it out.

Some of those 40 year old props were pretty cool designed... Some were thin and had excellent performance...If you raced them or ran them hard all day, they'd be "Toast"....But many new wheels, including ours, are thicked up so when someone put s thousand horse power to them, they don't tear all the blades off.

Run the numbers, gear ratio, rpm and pitch to speed... What is the slippage... Yes, our polished stainless look cool...but for just cruising and a hot run now and then...hell, brass is fine....

When I was a kid a thousand horse power was an ALLISON...now anybody can get a thousand HP... A 427... non blown, doesn't have that much torue..(Don't tell your Old Man..)..

ADD; I would like to think, that our cupped blades and designs are better than 40 years ago...but, Cold Fire was 25 years ago!!!
