FAQ Propellers
Product Information
PROPELLER BASICS:
Q. 3 or 4 blade?
A. A 3 blade propeller usually offers top speed performance while a 4 blade propeller provides maximum thrust and smooth cruising operation.
Q. Diameter?
A. Diameter is the distance across a circle encompassing all of the propeller blades.
Q. Pitch?
A. Pitch is the theoretical distance a propeller will move through the water for each revolution (i.e. a 21” pitch propeller should move a boat forward 21” for each revolution, assuming there is no slippage).
Q. Right hand or left hand rotation?
A. In most cases right hand propellers are used for single engine applications and one right hand and one left hand propeller are used for twin wngine applications to achieve better steering control.
Q. Cupped blades?
A. This is a technique used to enhance the performance of propellers under certain conditions: a cupped propeller will exhibit very high efficiency at high speeds as well as minimise cavitation under heavy loads.
Q. Rake?
A. Rake is a special design feature. Positive rake benefits from normal bow lift to permit the use of a larger diameter propeller, while negative rake can provide extra blade strength for use in very high speed applications.
Q. With an outboard, what height on the transom?
A. Re Transom mounting:
The mounting height of the ouboard on the transom is a critical factor in boat performance. For every inch that your motor is too deep it loses 200-250 rpm (approx), so ensure that at normal trim, full throttle the cavitation plate is just skimming under the water.
Q. How do I select the correct replacement propeller
A. Complete the “Propeller Selection” data sheet with as much information regarding the how you use your boat and any deficiencies experienced with your current propeller and our experts can make recommendations.
ALLOY Propellers:
Exclusive Solas squeeze casting process produces a stronger and tougher propeller than traditional die casting products. The propeller is then treated to 4 layers of superior protective coating (instead of one) to ensure excellent anti corrosion properties.
