Custom Propellers by S&S Propeller
4 Blade Katapult
- Katapult Series (4 blade)
- Engineered expressly for the Sportfish market. This propeller design offers minimum slip for high efficiency.
- Low cavitation and vibration levels enhance overall performance.
- Wide blade design incorporated with high camber provide utmost engine efficiency, thus increasing speed throughout the range.
5 Blade Katapult
- Katapult Series (Five Blade)
- The five blade Katapult propeller design was developed for Sport Fish and Express Cruiser applications with large reduction gear and limited clearance allowances.
- The five blade design will enhance acceleration and deliver ultrasmooth operation under way. The increased Diameter Area Ratio of this prop also enhances cruise speed at a lower rpm range.
- Diameter: 22" to 44 "
- Construction Material: Nibral
5 blade KatSkew.
3 & 4 blade also available.
- KatSkew Series
- Designed to eliminate turbulance.
- Camber is added to the trailing edges which lowers slippage and results in engine efficiency. This design is excellent for tunnel and high-performance applications requiring camber plus skew for a quick and quiet ride.
- Available in three, four and five blades
- Diameter: 26" to 50 "
- Construction Material: Nibral
5 blade HiSkew.
4 blade also available.
- HiSkew Series
- Designed for motor yachts exceeding 45 tons.
- The slightly cambered leading edges of this propeller, with 20 degrees of skew, alleviate prop noise and vibration. This, therefore, enhances engine & fuel efficiency resulting in better overall performance.
- Patterns are custom crafted to specifications
- Blade area ratios range from 87% to 125% depending on application.
- Available in four and five blades
- Diameter: 38" to 75"
- Construction Material: Nibral
5 blade Ultra Foil
- Ultra Foil Series
- Originally developed for vessels with tunnels, however these props have proven to perform on most hull configurations. Performance is excellent at cruise speed, due to the pitch configuration on trailing edges.
- We recommend using the foil design for vessels from 48 feet through 85 foot yachts and from 85 foot through 120 foot with high horse power ratings.
- Diameter: 28" to 44"
- Construction Material: Nibral
4 blade Ultra Crew
3 & 5 blade also available.
- Ultra Crew Series
- Expressly designed for Supply Vessels and Crew Boats.
- Its rugged construction gives the propeller durability, which cuts extensive downtime. The progressive pitch design maximizes performance, thus delivering excellent efficiency.
- May be cast in 3, 4 or 5 blade configuration.
- Diameter: 28" to 52 "
- Construction Material: Nibral
3 blade Hydro Thrust
4 & 5 also available.
- Hydro Thrust Series
- Designed for Workboats, Tugboats, Commercial Fishing Boats and various Displacement Vessels.
- Can be cast in 3, 4 or 5 blade configurations. DAR is available from .50 to .80, depending on application.
- Diameter: 32" to 92"
- Construction Material: Nibral
3 blade Kaplan
- Kaplan Series
- Designed for Offshore Vessels, Tugboats and Trawlers with Nozzle Setups.
- This propeller's design features heavy construction and modified leading edges that increase engine efficiency. DAR is available from .50 to .83, depending on number of blades.
- Diameter: 34" to 80"
- Construction Material: Nibral
4 blade Hi Rake
5 & 6 blade also available.
