Tohatsu Pro Series Outboard Propellers | Premium Performance for 60HP-250HP Marine Engines

Product Introduction

Engineered for professional mariners, Tohatsu Pro Series propellers deliver unmatched performance for mid-range to high-power outboards. These precision-crafted marine propellers combine Japanese engineering excellence with rugged durability for commercial fishing, patrol boats, and performance applications.

Advanced Material Technology

Marine-Grade Aluminum Alloy

• Special T6 heat-treated aluminum construction
• Reinforced blade roots with 20% thicker base material
• Micro-polished surface finish reduces hydrodynamic friction
• Impact-absorbing design protects lower unit components

Commercial-Grade Stainless Steel

• 17-4PH precipitation-hardened stainless steel
• Forged construction for maximum strength
• Computer-machined to 0.01mm tolerance
• Anti-fouling coating for saltwater applications

Professional Installation Protocol

1. Pre-Installation Inspection

• Verify shaft diameter and spline count (15-tooth or 17-tooth)
• Check gearcase oil level and condition
• Inspect thrust washer for wear patterns

2. Mounting Procedure

• Apply Tohatsu Pro marine grease (PN-TH-7700)
• Use torque wrench (65-80 ft-lbs for aluminum, 85-100 ft-lbs for stainless)
• Install new cotter pin and bend properly
• Mark torque position with paint pen for visual verification

3. Post-Installation Testing

• Conduct 30-minute break-in at varying RPMs
• Verify maximum RPM matches specifications
• Check for vibration at all speed ranges

Critical Safety Measures

• Impact Protocol: Immediately reduce speed after any underwater strike
• Corrosion Prevention: Apply anode protectors for saltwater use
• Load Monitoring: Never exceed recommended pitch for engine size
• Storage Requirements: Hang vertically in climate-controlled environment
• Wear Indicators: Replace at first sign of blade erosion or pitting

FAQ

Q: What's the difference between standard and commercial propellers?
A: Our Pro Series features thicker blades, reinforced hubs, and special alloys for continuous duty cycles.

Q: How does blade area affect performance?
A: Larger blade area (up to 15% more than recreational props) provides better thrust for heavy loads.

Q: What maintenance is required for saltwater use?
A: We recommend monthly inspection of anodes and bi-annual professional balancing.

Q: Can these propellers be repitched?
A: Yes, our authorized service centers can adjust pitch within ±2" of original specification.
