Basic Propeller Information
3 OR 4 BLADES?
A 3-blade propeller usually offers top speed performance while a 4-blade propeller provides a maximum thrust and smooth cruising operation.
RIGHT HAND OR LEFT HAND ROTATION?
In most cases, right hand propellers are used for single engine applications and one left hand propeller is used for twin engine applications to achieve better steering control.
DIAMETER:
Diameter is the distance across a circle encompassing all of the propeller blades. (See Original Equipment Considerations item 2 below).
CUPPED BLADES:
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 minimize cavitation under heavy loads.
PITCH:
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).
RAKE:
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.
ORIGINAL EQUIPMENT CONSIDERATIONS:
1. Determine the year, brand, model and horsepower of your motor.
2. Calculate the diameter of the OEM propeller by measuring from the center of the shaft hole to the tip of a blade x 2 (Example: a measurement of 7-1/4” - a diameter of 14-1/2”).
3. Is the type of material aluminum or stainless steel?
PERFORMANCE CONSIDERATIONS
1. Type of boat (cruiser, ski, runabout, bass, pontoon)?
2. Prop on boat now (brand, model, diameter, pitch, cupping)?
3. Engine RPM at wide open throttle (WOT)?
4. Speed of boat over water at WOT?
5. Normal operating altitude (motors lose 3% of power per 1000 ft.)?

Aluminum Propellers Products
SOLAS employs state-of-the-art squeeze casting processes to enhance the strength and durability of their aluminum propellers, surpassing the capabilities of conventional die-cast props. SOLAS aluminum propellers boast four layers of paint, a testament to their commitment to outstanding anti-corrosion performance.
Stainless Steel Propellers Products
SOLAS stainless steel propellers are distinguished by their exceptional composition, containing the industry’s highest concentrations of chromium, nickel, and molybdenum. These corrosion-resistant materials significantly enhance the stability and longevity of the propeller blades. SOLAS stainless steel products are synonymous with outstanding performance and remarkable durability.
Rubber Bushings Propellers Products
The Rubex 2-piece propellers are meticulously crafted to eradicate the unwanted chatter and vibrations often experienced with rival hub systems. These robust and long-lasting rubber hubs possess the remarkable ability to absorb up to 10% of impact, resulting in smoother shifting and minimized damage caused by propshaft shock upon collision with submerged objects. Each Rubex hub kit is thoughtfully equipped with the necessary hardware for hassle-free propeller installation onto the propshaft.
