Piranha Propeller, yes or no


The Treasurer within my dive club wants to put a plastic Piranha Propeller on our 5.5m dive boat (Yamaha 90) as we've dinged out current Ali one.

I can't find too much via the search function so a simple question if I could please.

Will it power the boat effectivly?
Will it last?
Would we be better off sticking to an Ali prop?

Many thanks

I have a 4 Blade Puranha prop that I carry as a spare in the boat for my DT200EFI. I brought it VERY cheap off ebay a few years ago, and it came with a set of extra blades.

I've tried it a couple of times, and it appears to be very good, but I've not tried it for any length of time.

The main advantage for me is it's weight when carrying it as a spare, and of course the fact that I can also carry the spare set of blades, so that if I have a really bad day I do in effect have 2 spare props, all for less than the weight of one Ali prop.

When using it as a full time prop you could obviously carry a spare set of blades instead of a full spare prop.

That doesn't answer your question really, but it may be of some help.

When I considered buying one a few years ago, I think it worked out more expensive than an Alu one. However, you have got the functionality of swopping a broken blade yourself.

I wouldn't put one on a Yam 90.

Wait for Doggypaddle to turn up to tell you how bad my Piranha was on his 80. His experience means it's been relegated to emergency get you home spare. Apparently it was so bad it wouldn't make much past 20 knots on his 5.4.
Need spares,consoles,consumables,hire,training or even a new boat?
