Mercury High 5 prop

I currently have a standard 21p stainless prop on my opti 175 and saw this whilst nosing on ebay.

High Five Propeller Stainless Steel | eBay

Are these props any good?What is the benefit over a standard 3 blade prop? Whats a fair price for it if any good?

Thanks

Hi Miller,

we tried one on our 150 Opti (21 pitch) and it wouldn't rev out (not that it won't for you).... I bought it having just been reconditioned by Steel Developments ....

Paid 150 for it and sold it on for the same.....

Multiblade props are a bit of a gimmick IMV. The idea is that you'll get a stronger pull out, but as with swings and roundabouts, if you gain on one, you'll lose on the other. Top speed will suffer.
Stick with your 3 blader.

When we were testing props on the race boat we found that going from a 3 blade to a 4 blade meant we had to drop pitch by 1 or 2. I suspect the same applies to a 5 blade prop, so I am guessing a 21 5 blade prop would be somewhere in the range of 23 3 blade prop.

Great for pull out, but not so good for top end speed.
