Industry Standard Bronze Bushing | General marine engines (low-to-mid HP) | ASTM B124 Bronze, Load Capacity 4000 N Corrosion Resistance (Saltwater Exposure: 500 hours) | Cost-effective, widely compatible with older engines | Lower load capacity, moderate corrosion resistance in harsh conditions |
Our Base Stainless Steel Bushing (EP07010803.0 Base) | Honda Outboard Motors (90-175HP) High-torque applications | 304 Stainless Steel (ASTM A240) Load Capacity 5000 N▲ Corrosion Resistance (Saltwater: 1000+ hours▲) | ▲ 25% higher load capacity than bronze Resists saltwater corrosion better | Slightly higher cost than bronze |
Our Advanced Stainless Steel Bushing (EP07010803.0 Advanced) | Honda Outboard Motors (175-250HP) Heavy-duty use | 316 Stainless Steel (ASTM F138) Load Capacity 5500 N▲▲ Corrosion Resistance (Saltwater: 2000+ hours▲▲) | ▲▲ 37.5% higher load capacity than bronze Best-in-class corrosion resistance | Highest cost tier, requires precise installation for optimal performance |
Composite Bushing | Small engines, freshwater use | Glass-Epoxy Composite (ISO 12232) Weight 0.8 kg▲ (vs 1.2 kg steel) Moisture Absorption <0.2% | Lightweight, cost-effective for low-load applications | Limited load capacity (3000 N) Prone to wear in high-torque scenarios |
Ceramic Coated Bushing | High-temperature environments | Zirconia Coating (ASTM C349) Temperature Resistance 800°C▲ Friction Coefficient 0.10▲ | ▲ 20% lower friction than steel Excellent heat resistance | Fragile, expensive, incompatible with Honda’s standard mounting systems |
Plastic Bushing | Low-cost, non-corrosive freshwater use | POM Acetal (ASTM D4018) Moisture Absorption <0.1%▲ Weight 0.5 kg | Inexpensive, lightweight, ideal for freshwater | 2000 N load capacity Degrades in saltwater, unsuitable for Honda’s HP range |
