I got lucky!
In prep for my Bahamas trip, I called my diver to take my prop off as it was having a vibration issue. It needed refurbishing. What I didn't know at the time was it's a bronze prop. The refurbishing cost is substantial, BUT, my diver said he has only seen 3 in his career and not only is it the best, it will last a lifetime!
There has been so much guessing with this vessel since the day I bought her because it was an estate sale, no manuals, etc. I finally got lucky!
I love her more everyday!

I'm confused. Most props are some form of bronze.

Nibral is the choice for most recreational props on the boats commonly found on TF. Nickel, bronze and aluminum alloy.
Donna, how did the diver know the difference between a Nibral vs a bronze prop?

I think NIBRAL and such are stronger and thus harder to reform than simple tin bronze so my confusion continues.

Couldn't resist ... 99% of the propellers on cruising boats are "Manganese bronze" which is actually classed as a brass due to it's high zinc content and subject to dezincification if cathodic protection systems are not kept up or if stray current is an issue. Nibral is a proprietary bronze alloy and quite rare due to their high cost. True bronze props are very rare again due to their very high cost.

These are very popular and what is on my boat. The original was what they consider "pink" so I purchased a reconditioned Michigan prop. What I didn't know at the time I installed it was described in a recent post, so I need to check the fit at my next haul out.

The "pink" colour indicates de-zincification of a manganese bronze (brass) propeller.

Stupid question but I cannot resist... is there any usage of plastic for propeller (except for inflatable fishing boat with outboard)?

And I thank you. Yes it is true bronze.
Didn't feel like explaining it after the "the lady didn't get played", comment.
Almost all the work on the boat including engine work is done by me and if I don't know, I ask. I can assure anyone that it would take a village to play me. I like my research too much.

Wifey B: Are you repeatedly lucky or is it your attitude? You love your boat and you have worked your...ok, careful girl, language......you've worked very hard getting it ready. You've invested so much of you in it. Others might be whining about their horrible luck that they have to spend money with a prop shop. You're happy it's there being repaired and then the news you received you accepted as another positive. Thankfully, boatpoker was able to respond to all the doubters. However, you were going to be happy with whatever it was, because you love your boat, you knew there were some costs ahead and costs owning it, and you're focused on the fun ahead.
Oh, I hope you just have the best time ever in the Bahamas.

Wifey B: Some ladies aren't easily played. They may be beautiful and perceived automatically by some as not being tough, but you start trying to play them and you'll find out the hard way. I'd never underestimate Donna.

Wifey B: Always. Just got home from a trip to Miami. Short trip but two days there with our best and closest girlfriend and just the three of us enjoying a trip together. Were going to Key West initially but decided to stop short due to sea conditions.

I'm certain your boat prop looks good in bronze, Donna! And, all tuned up, that prop should give you ears of great cruzen!

I thought bronze was normal and common in low horsepower applications and Nibral in higher horsepower. Not being picky here, I do love to be informed. My vessel only has 50 hp and has a 3 bladed bronze prop, my friend's NT 32 has 220 hp and his is five blades and Nibral. I thought the bronze props were lower cost as well... When I priced a new prop for my boat (just for fun) it was only offered in bronze.
