Available in shaft sizes of 3/4” – 8” (100mm – 200mm) in diameter with a stern tube of up to 10 ½”. We can accommodate a stern tube flange of up to 18”.
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. Available in shaft sizes of 1 1/8” – 5” (30mm – 127mm) in diameter.
The Lasdrop Elite is a compact, 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 Elites incorporates a water lubricated alignment bearing in the housing to keep the unit properly aligned with the shaft. There is a compartment that is secured to the housing that encompasses a back-up seal, making it changeable in the future without the need of removing the shaft or entire unit. 2nd back-up seal in compartment is available as an option.
