Trust the Pros
The days of fixing props with an anvil, welding, and paint are long gone. Modern props need skilled professionals for proper reconditioning. Tri County Propeller, a trusted shop and proud member of the National Marine Propeller Association, offers certified expertise you can rely on.Inside Tri County Propeller
New Shaft Fabrication
Our experienced machinists craft shafts to match client samples or provided specifications. Tapers and threads are made according to SAE International J755 standards, the global authority in mobility standards. We also offer metric sizes and custom machining to meet the specific needs of your vessel and application.
Dynamic Balancing
After reconditioning your propeller blades on our MRI, they undergo dynamic balancing. This computerized, high-speed process provides a detailed report on the propeller’s balance before and after treatment. Dynamic balancing can detect imbalances that traditional static methods miss, ensuring your propellers run smoothly without vibration.
MRI Scan
The Hale Propeller Measurement Recording Instrument (MRI) is one of the most advanced and versatile computerized 3D propeller measurement devices available. With its comprehensive reporting capabilities, the MRI allows technicians to accurately document the condition of a client's propeller. This ensures optimal repairs, with both initial and final scans available for client inspection and kept on file for future reference.
Custom Welds
Our experienced welders specialize in welding shafts, propellers, and custom projects to meet your needs. Whether it's stainless steel, bronze, NiBrAl, or aluminum, we can weld it. From custom tools and housings to anchors, lower units, boat ladders, railings, door handles, and more—if you can name it, we can weld it!
Propeller Welding
Propellers often require welding during reconditioning to address stress cracks, pitting, cavitation burns, missing material, or thin blades that need reinforcement. We also weld overlays on shafts when the seal or bearing housing areas are undersized or damaged.
Shaft Reconditioning
Shafts are cleaned and inspected by our experienced machinists using dial indicators and micrometers to identify any bends or areas where the shaft may be undersized. After straightening, we fit and face the coupling to ensure a perfect alignment.
Machine Shop
In addition to working on shafts, couplings, and propellers, our full-service machine shop can repair and fabricate any custom part you may need. All we require is a sample or an accurate schematic to get started.
Hydraulic Propeller Press
The hydraulic press offers a faster, more efficient way to recondition and repitch larger props. It performs all the straightening and adjustments without the need for heat, preventing any hammer marks.
Propeller Grinding
Before balancing, reconditioned props are polished in our grinding room. We remove hammer marks and imperfections, then finish with Scotch Brite for a smooth, shiny pattern. If Propspeed is to be applied, we use 80-grit sandpaper for the final finish.
Sand Blasting
The first step in the reconditioning and quoting process is removing any excess sea growth from your propellers, such as algae and barnacles. Clean, smooth blades are essential for an accurate MRI reading. We also offer sandblasting for hardware upon request.
Lower Units
We have a dedicated bay exclusively for our outboard clients, where we recondition props, straighten outboard shafts, weld cracks, and more. Whether it’s a conventional lower unit, dual prop lower unit, or IPS lower unit, our expertise ensures you’ll be back on the water in no time.
Heating
For severely bent propeller blades, we apply heat to make the metal malleable. Once it reaches the ideal temperature, we carefully straighten the bend—an essential step in the repair process.
Pitch Block
After heating, the propeller is placed on a pitch block—a metal mold with the factory’s exact blade shape and pitch. The technician then uses specialized hammers to reshape the blades, restoring the propeller to its original design.
Skeg Repair
Damaged your skeg? Our machine shop custom fabricates an aluminum skeg to match your lower unit. It’s then expertly welded on and ground down to restore its original shape.
Polishing
Our polishing machine gives your propellers a like-new, mirror finish! Whether stainless steel, bronze, or nibral, we’ll have them looking clean and shiny!
Propeller Rehub
Spun hub? No problem! Our experienced technicians can quickly replace it to get you back on the water. We offer OEM options for select brands and high-quality aftermarket hubs. Turnaround time is as fast as same-day or next-business-day pickup!
Inventory
At Tri County Propeller, we maintain a vast inventory, including new and used inboard/outboard props, cutlass bearings, and essential hardware like tiller arms, packing boxes, shaft seals, nuts, bolts, and cotter pins. We also stock sacrificial zincs of all types and sizes to protect your vessel from electrolysis and corrosion. Special orders are available upon request.
Shafting Material
We use high-quality, American-made Aqualoy-17, Aqualoy-19, and Aqualoy-22 stainless steel for all our shafts. Sizes range from ⅞” to 3” and larger. If a size isn’t in stock, we’ll order it, and it arrives within 3-4 business days for a quick turnaround. For in-stock materials, we can complete your new shaft in just 1-2 business days!
Quality Control
Our dedicated team ensures your propellers and shafts are repaired with precision through frequent inspections at every stage. We treat your vessel as if it were our own.
Storage
Once your props are ready, they’re securely stored in our pickup area, conveniently located next to the main office. Here, you can inspect the final results and complete any pending payment. For easy loading, we have a forklift and crane on hand to get you quickly on your way.Visit Us
