Another prop question

[8318]

The 18 is back on the water with the new motor running great.
The 26 laser 2 was spinning up over 5 grand way before the boat was wide open.
I was given this prop (see attaches pict) all I know about it is the pitch is 27 in and it is a 4 blade.
I did some testing with it the other night and got 73 mph off speedo on the boat at 4600rpm.
Do any of you know what tis porp is who the manufacture is?
I think it is a bit too big,way too fast at idle.

Is it a good prop?

Yes it is a good prop. If it is the best or not is depending on the application. Some boats love them and a fed don't. One 22 that I know of hates it and other love it. BTW not the driver but the boat. Me I have had 16 different designs on my boat that I like, 3 of which I love. Wait I have a new one a just designed 4 blade that is quickly becoming the best so far for all a round. More on that later.
