Oziles' proudly offers Piranha propellers. These are composite props with interchangeable blades. The main benefit is if you damage a blade, you can replace just the blade at a fraction of the price. You can also try different pitches, without changing the hub. Typically 5 pitches are available for any given hub. The hubs are guaranteed for life! We carry props for inboards and outboards, ranging from 6Hp and up. Call us for more info and suggestions for prop sizing. Prices for Piranha propellers at Oziles' are comparable with an aluminium propellers.
