1" Bullflex Flexible Shaft Coupling - Type 4 (4.3 HP Max. HP/100 Shaft RPM)

Designed for smaller stern gear installations, the flexible rubber element of the Bullflex flexible coupling ensures low-noise vibration-free transmission, without backlash between the engine and the propeller shaft.

A special centering ring allows high shaft revolutions, and even in reverse gear, the shaft will remain perfectly centered.

• Optimum damping of vibrations
• Non-tapered clamping hub ensures easy installation and disassembly
• Misalignment of up to 2° permissible (misalignment restricts max. engine RPM, however)
• Secured against shearing off, axially and radially
• Eliminates propeller shaft backlash
• Special adapter flanges for Volvo, Yanmar and Kanzaki are available as options
• Note: Specification Table lists maximum horsepower for recreational use; for commercial use max. HP is 20% - 40% lower, please call if you have questions or need advice; 800-426-6930
