Product Description

Lasdrop 2" Gen II Shaft Seal

The Gen II offers exclusive features that make it the premier shaft seal on the market with the culmination of more than a quarter century of experience in shaft seal design. The Gen II offers a unique ball-bearing drive system that allows the seal ring to "float" and remain in constant contact with the carbon graphite seal surface, resulting in a seal that's impenetrable to water.

The Gen II uses a 316-marine grade stainless steel spring to provide pressure to the seal surfaces. Together, the spring and seal ring rotate along with the shaft, and remain secured in the Clamp/Pressure housing.

Each kit includes AWAB hose clamps that are made of 316 stainless steel with rolled band edges to eliminate risk of damage to the hose. The non-perforated band provides twice the tensile strength of a regular clamp.

  • 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.

  • Built into the friction ring assembly is a cutlass bearing to ensure proper and constant alignment to the shaft.

  • The Clamp/Pressure Assembly secures the assembly around the shaft, preventing the galling or damage to the shaft that can occur with setscrews.

  • The 316 stainless steel seal ring floats on a ball bearing drive system, maintaining complete contact with the carbon graphite seal surface.

  • Solid brass hose barbs.

  • AWAB hose clamps are 316 stainless steel, manufactured with indentations rather than perforations, providing twice the tensile strength and eliminating friction as in regular clamps.

Installation Instructions

How to Install Lasdrop Gen II Shaft Seal

Note: Be sure not to damage the inner lip seal while unpacking and handling.

  • Unbolt the shaft coupling from the engine coupling then remove the shaft coupling from the shaft. Removing the shaft coupling may be difficult.
  • Insert a spacer (smaller than the shaft diameter) between the shaft and transmission. Re-tighten the coupling back onto the transmission.
  • Remove your old stuffing box. If your boat is equipped with a bolt on or rigid type stuffing box, follow the instructions below:
    • If your boat is equipped with a bolt on or rigid type stuffing box you will need to reverse the plate and tube that are used to compress the packing. Once reversed, the connection hose can be fitted over the tube.
    • When re-attaching your reversed plate and tube, seal the two surfaces so that no water can leak through.
    • If your old stuffing box was threaded on, you will need to cover the threads with a liquid gasket material to prevent the threads from cutting into the connection hose.
  • Once stuffing box is removed, clean shaft as thoroughly as possible with very fine sandpaper (400 to 600 grit) and remove any sharp edges or burrs.
  • Slide the Friction Assembly over the shaft and connect it to your stern tube with the provided stainless hose clamps. An insert may be necessary for proper fit.
  • When mounting your friction assembly, arrange connection hose so that there is a minimum amount of pressure on the inner alignment bearing (inside the friction assembly). This should only have to be done if shaft is not centralized with the stern tube in a fairly extreme manner.
  • Mount connection hose crooked to relieve any major pressure caused by misalignment. When tightening hose to friction assembly with clamps, DO NOT over tighten.
  • If the end of your drive shaft is not tapered, you will need to use the included installation plug to install the clamp/pressure unit over the shaft. Use liquid soap to lubricate the inner lip seals then place the installation plug next to the lip seal inside the unit.
  • Carefully slide the assembly onto the shaft. You will need to push the plug out the back of the assembly using your finger as a guide. Re-install the coupling onto the shaft and bolt the assembly back onto the transmission.
  • Slide the clamp/pressure assembly into contact with the carbon friction assembly and mark this “neutral” position with a marker.
  • While using the “neutral” mark on the shaft, compress the clamp/pressure assembly ¼”. Keep the assembly onto the shaft by tightening the two bolts on the housing.
