PROP AL MNT 9-20HP 4B 09

SOLAS uses a state of the art squeeze casting process to make our aluminum propellers stronger and tougher than traditional die cast products.As shown below with 400x magnification of a propeller blade root cross-section the squeeze cast propeller is almost non-porous with finer grain size than the die cast propeller.SOLAS aluminum propellers have 4 layers of paint. Using superior coatings and a high-tech painting process ensures excellent anti-corrosion performance.SOLAS aluminum propellers are exposed to over 500 hours of testing in a salt water spray tank. This testing simulates more than 6 months of normal salt water use.Traditional Rubber hubFour blade aluminum propellerExclusive Solas squeeze casting processWide blade design specifically for 4-stroke enginesIncreased static thrust for heavy loads & maneuverabilityGreat stern lift and mid-range performanceMFG# 5113-093-09 511309309 UPC# 824375008443 MFG# 5113-093-09 511309309 UPC# 824375008443.
