At MARINE PROPULSION REPAIRS we are committed to repair bronze propellers that meet or exceed our clients' requirements, guaranteeing our repair quality and continually improving the efficiency of our processes and quality systems.
We have over 60 years of experience in both the manufacture and repair of propellers.
With the rise in metal prices, propeller repair has become an economic necessity. The increase in repair demand, including several contracts with the U.S.C.G. to repair its propellers and CPP blades, speaks highly of the confidence our clients have in the quality of our repair services, therefore, we decided to create new facilities and infrastructure exclusively for this purpose.
Our staff has the approval of different classifications societies to ensure the professional-quality work.
We use state-of-art technology and highly-specialized staff to make our repair processes more efficient and precise.
Services we offer
Repair of propellers that meet established international norms, while offering the following services:
- Straightening of battered areas.
- Main dimensions readings.
- Pitch modifications.
- Dye check (NDT).
- Static or dynamic balancing, as needed.
- Analysis tests of chemical and mechanical properties.
- Regeneration of damaged areas by welding or grafting (if required).
- Blade shape modifications (open wheel to nozzle application and vice versa).
- On site urgent propeller repair to large vessels, such as tankers, cruise ships, etc.
Repairs may be done in-house, afloat or on site.
A preliminary diagnostic test is done of the condition of the propeller, to determine the best work strategy to use according to the damage or modification to be done, which may include: pitch correction, thicknesses, widths, implants, balancing, etc.

We have a long track record of satisfied clients that have trusted us to restore their propellers to their original working condition or increase their efficiency.
Materials and alloys
We repair bronze, NiBrAl, Aqualloy and stainless steel propellers. We use the right weld according to the alloy of the propeller to assure the proper adhesion with the adequate mechanical properties.
Our repair service is controlled by international standards ISO 484 Class S, I and II, and repair methods endorsed by various certification agencies such as DNV, ABS, Lloyd's Register, CCS, Germanischer Lloyd's, RINA and Bureau Veritas.
At MARINE PROPULSION REPAIRS we are experienced in the manufacture and welding of graftings, making this process more efficient compared to the normal process of filling-in completely with weld.
