If your looking for a spare prop then it is ok.
In terms of efficiency and performance - Bad.
It is a cheap prop for a reason.

Why do you want one?
What boat do you have?
What HP engine do you have?
How do you normally use the boat (load, rpms, etc..)?

If you want the best performance your boat can provide you want a good SS
prop. Now you have to decide 3 blade or 4 blade (or in some cases 5 blade).
3 blade gives better top end. 4 blade gives better acceleration and hole
shot and bow lift.

In another thread there is a report of a Pirhana Prop that threw blades
for no apparent reason.

Their web site is

Are there any other opinions about them?
