Perfect alignment of engine and propeller shaft often tends to be a rather time consuming affair, but the Bullflex comes to the aid of the installation engineer. Even with a misalignment of 2°, the shaft will remain perfectly centered onto the flange of the reverse gearbox. On account of a special centering ring, high shaft revolutions are entirely possible and even in reverse gear, the shaft will remain perfectly centered.
I am looking for a flex coupling to my pleasure boat. Flange from a Capitol gear. Dimensions: Outer flange dim 4,3/4 inch, cc diameter for 6 nos 7/16 bolt holes 3, 7/8 inch. Max rpm on gear flange, 733 rpm and max torque 71 kgm. Narrow installation place, wishes a max total diameter of the coupling of max 200 mm. Diameter of propeller shaft, 50,0 mm. Thrust from propeller will pass through the coupling. Boat speed max 8 knots, displacement 11 tonnes. Propeller dia./pitch 31x20". Proposal?

Sorry we don’t carry a coupler that meets these specifications at this time.
