This week we are featuring the Gen II Shaft Seal
from Lasdrop.  These seals are built from the highest marine quality materials and
components for a safe, lasting and non-damaging seal that will log some serious time on
your watercraft before ever needing to be touched.  This is also a great time to talk about
Shaft Seal retrofits as you pull your boat out of the water for the season.

WHY WE LIKE IT: Lasdrop's Gen 2 is a unique, water-lubricated ball-bearing drive seal
system that allows the seal-ring to "float" and remain in constant contact with the propeller
shaft so there isn't water getting into your bilge room.  

This is achieved by using a 316 marine-grade stainless steel spring to apply pressure on seal
surfaces.  The spring and seal ring rotate with the shaft.  Dual "u-cup" seals rotate behind
this, completely denying the passage of water.

These components remain secure with a clamp/pressure housing that does not utilize
screws to clamp onto the prop's drive shaft.  There will be no galling or damage to the
propeller shaft with the Gen 2.

Lasdrop Gen II friction ring housing is constructed from durable copolymer with built-in,
water-lubricated bearings to protect the carbon graphite friction ring from damage and
ensure proper alignment on the shaft.  Seals include dual injection ports & necessary

More than 25 years of experience went into the Gen II, and it shows.  The Lasdrop DrySeal
shaft seal is the highest quality propeller shaft seal available.
It is considered by many industry leaders as: “the most reliable shaft seal on the marine
