1-3/4" Bullflex Flexible Shaft Coupling - Type 12 (12.8 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.

• Misalignment of up to 2° permissible (misalignment restricts max. engine RPM, however)
• Secured against shearing off, axially and radially
• Eliminates propeller shaft backlash
