I have a prop here that I haven't tried. I had a smaller bravo 24p 4 blade on my boat and i needed to step up to a bigger prop. I thought they were the same, luckily the boat shop lost all the parts to my last prop. So I was looking for a hub/installation kit and noticed that they may be different. The Mach Stern Driver is a 15x28 and has a marking of 0779 on the back of the prop. I have a bravo 1 on my boat what all is needed to install this part and what is different? Ill post a couple pictures in a minute from my phone.

Thats should go right on, you need the big disc that goes behind the prop, then it should slide right on.

My stern driver prop had a brass piece on top that had the lugs in it to bend the lock tab ears into.

the same brass disc that goes/comes on a bravo prop hub kit?

can you post a picture?

Thats the one.
