Rice Propulsion has a full line of propellers to meet any requirements. All types of bronze (Mn Bze, NiBral or Aqualloy), from 30″ up to 160″ diameter, ISO class II, I and S. Every single propeller is designed with the latest technology available that meets the most demanding standards. ISO 9001 certified.
With over 4,000 different models available for their product lines covers the demand required by the market, reaching all countries.
We offer exclusive designs according to the needs of each one of its clients, such as the Heavy Duty River Propeller.
Controllable-pitch blades are manufactured to the client’s specific requirements.
Our specialized repair shop is equipped with the latest technology to reconstruct your propeller or blade to design.
For the propulsion system we provide pieces such as the hydrodynamic nut, shafts, bronze rubber bearing, stern tube bearing, stern tube, sleeves, stuffing box, couplings and others.
Controllable-pitch blades are manufactured to meet or exceed maximum quality standards. Replacements or spares can be fabricated from a sample blade in case there is no drawing available. Our specialized repair shop is equipped with the latest technology to reconstruct your blade to design. Skilled personnel have been trained specifically to evaluate, repair and report any damage in order to find the best repair option. As reference we overhaul CPP blades for the United States Coast Guard (USCG). You can be sure that your blades will be repaired to the highest standards.
3 TO 5 BLADES 30” - 60” DIAMETER CRUCERO offers you: PERFORMANCE, COMFORT AND EFFICIENCY. A WAY OF LIFE AT RICE. Designed for pleasure craft and crew boats, our Crucero propeller has become one of our most popular models. The Crucero will help your boat reach its top performance levels and planning velocity while eliminating hull-damaging vibrations. It provides a smooth and comfortable ride for you and your passengers.
3 TO 5 BLADES 30” - 160” DIAMETER DELFIN offers you: PERFORMANCE - Most versatile. - Its refined design offers high resistance, inspired in the propeller type “B-Troost”. - Used Worldwide on fishing, supply and workboats. - Its flexibility is able to cover all types of use, because it can be manufactured with 3 to 5 blades, according to the type of use or application given. POWER - Blade area may vary without changing the number of blades to obtain greater thrust or more speed. - 3 to 7 hydro-dynamic cross-section blades, with integrated hub shapes.
3 TO 5 BLADES 30” - 160” DIAMETER The Kaplan propeller is another example of our most advanced technology. This propeller is designed to be used with a nozzle in order to give shrimpers and workboats more thrust, by considerably increasing the efficiency of propellers carrying heavy loads while working at low speeds. KAPLAN offers you: PERFORMANCE - Advanced technology. - High efficiency with nozzle. - More thrust from propellers carrying heavy loads at low speeds. - Mn Bze, Stainless Bze or Aqualloy. With our leading technology, we can offer you more efficient systems.
3 TO 5 BLADES 30” - 160” DIAMETER KA-SPEED offers you: PERFORMANCE - Reduced force-excitation level of the propeller. - Offers excellent output improving blade stress distribution. - Smooth and silent operation (better than Kaplan propellers). - Blade area ratio according to your needs. The Ka-Speed was developed by adding the advantages of skewed propellers to the traditional Kaplan style. It was conceived to be installed into our Rice Speed Nozzle for best performance, but it may also be installed in a Kort nozzle.
Marine Propulsion Repairs
Rice Propulsion not only has professionalized the manufacture of propellers, but also offers repair and maintenance services. New exclusive alternate facilities offer specialized service with state-of-the-art equipment and advanced technology, where highly qualified staff thoroughly analyze the damages and dimensions of the propeller. Once the evaluation is made, they proceed to its repair by using welding processes and on occasion the manufacture of implants, resulting in fully-restored pieces to their original working condition. Such service has won-over the trust of the US government, for whom a great number of propellers are repaired annually for its Coast Guard.
3 TO 5 BLADES 30” - 160” DIAMETER The Nautilus propeller is one of our latest developments. Its skewed design reduces the propeller pressure pulses to minimum level, allowing the smoothest and quietest operation. It is ideal for applications where underwater noise and vibration requirements are critical. NAUTILUS offers you: PERFORMANCE - Low noise and vibration. - Smooth and quiet operation. MED-HIGH SPEED - Blade area ratio may vary to meet your requirements. - 3, 4 or 5 blades, ISO Class S, from 30” to 60” in dia., Class I and II up to 150” in dia.
All propellers are manufactured and designed with the latest state-of-the-art technology available and meet the highest quality standards. With more than 4,000 models available for its different product lines, it covers the required market demands. To cater to different needs in the marine market, Rice Propulsion offers a range of designs in commercial propellers, standing-out among them are: Delfín, Titan, Ka-Speed, Nautilus, Crucero and Kaplan.
Heavy Duty River Propellers
With the objective to provide better service, Rice Propulsion manufactures exclusive designs according to the needs of each one of its clients. Such as the “Heavy River” propeller, specially-designed for use in the Mississippi River, for heavy usage. Its blade’s form allows it to be used both as a free propeller and with a nozzle.
3 TO 5 BLADES 30” - 160” DIAMETER TITAN offers you: PERFORMANCE - Hard working propeller. - Built to take heavy demands of tugs, workboats & heavy duty vessels. - Greater thrust in a smaller diameter. HEAVY-DUTY - Blade sections are larger than standard propellers for vessels with limited propeller space. - This powerful and efficient propeller made with oval transversal cross sections and a larger impulse surface allows a high-powered transmission. - 3, 4 or 5 blades from 30” up to 160” diameter.
