LasDrop Gen II Shaft Seal 2 1/4 in. Shaft G214-3 Gen II Shaft Seal 2 1/4 in. Shaft 3 in. Stern Tube The Friction Ring assembly is mounted with a rigid connection hose and uses a carbon graphite sealing surface all encased by a durable copolymer housing Cutlass bearing ensures proper alignment to the shaft even if the shaft itself is not aligned The clamp pressure assembly secures the assembly around the shaft preventing galling or damage to the shaft that can occur with set screws The 316 stainless steel ring floats on the ball bearing drive system maintaining complete contact with the carbon graphite seal surface Seal ring features two rubber/fiber U-cup seals that rotate with the shaft and never wears out Hose barbs are constructed of solid brass and are coated to prevent corrosion Hose clamps are manufactured of 316 stainless steel with indentations rather than perforations providing twice the tensile strength and eliminating friction as in regular clamps Two hose clamps provide for each connection point Virtually no metal to metal contact eliminates the risk of electrolysis
