The Lasdrop DrySeal is a compact, economical lip seal designed for quick and easy installation. The lip seal, made specifically for marine use, is in constant low friction contact with the propeller shaft, preventing water from passing in your vessel. As in all Lasdrop models, the DrySeal incorporates a water lubricated alignment bearing in the housing to keep the unit properly aligned with the shaft. There is an optional back-up seal available that can be installed during the original installation changeable in the future without the need of removing the shaft or unit.
Split-face plate makes it easy to replace inner lip seal with an optional back-up seal without the need for special installation tools.
Seal housing is constructed of a durable copolymer with built in water lubricated bearing insuring proper alignment to the shaft.
Optional Back-up seal rotates freely on the shaft until replacement is needed.
Each kit includes AWAB hose clamps that are constructed 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.

• Do not use oil or grease. During operation on a mechanical face seal, water hydroplanes between the seal surfaces for cooling and lubrication. This will distort the hydroplaning and will cause a spray or mist during operation.
• Be cautious not to scratch, chip or the like to the seal surfaces. This will also cause an interruption in the hydroplaning.
• Use liquid hand soap for ease of assembly.
• When any service is performed, it is recommended the vessel be out of the water.
• Do not exceed recommended compression. Orange (current) bellows model ½”, Black bellows ¾” and Generation II ¼”.
• Do not remove shaft from coupling or removal of engine while vessel is in water. This may lead to seal surfaces opening up.
• Do not tighten factory installed hose clamps on friction ring assembly. If needed contact factory.
• Do not remove or tighten hose barb in seals using OIN (Oil Impregnated Nylon, green in color) as a friction ring assembly. Contact factory.
• Periodically insure water injection is present during engine running at all speeds.
• When vessel is out of the water for any period of time, it is recommended seal is washed down with fresh water.
