Ordered a Piranha Propellers Complete A-Series 4 Blade Propeller from Macomb Marine Parts and even though we’re international, it arrived in just over a week — fast and reliable service. The propeller itself is a real lifesaver. We had the same model before, and after hitting a rock that damaged two blades, we were able to swap them right on the water and make it back to the marina without issue — something you simply can’t do with a regular aluminum prop. For peace of mind we decided to buy a complete new set (hub and blades) since an impact like that could cause hidden damage, but the system really proved its worth.
I couldn’t find a Piranha propeller dealer near me in Canada but found Macomb Marine Parts who could deliver to me. The order process was smooth and I was even contacted via email for clarification regarding blade shape and they were very helpful in choosing the best shape for my purposes.
I can’t comment on the prop’s performance yet as we haven’t had the boat in the water yet.

Would have been 5 stars but....
Would have been 5 stars but, I did not receive a promotional sticker with my $2000 drive unit. Just kidding, everything was great!
