The Gen II shaft seal from Lasdrop uses a ball-bearing drive system that allows the seal ring to float within the housing and keep in constant contact with the carbon graphite seal surface, making it impenetrable to water. Also, by using a spring-loaded housing instead of a bellows, the Gen II never has to have its bellows replaced (see how that works?). All units have dual water injection ports, and are available for shaft sizes ranging from 1 1/8 to 5 inches.
Talking about windows on boats, there’s a lot to consider. Will the new ones hold up and be easy to maintain? Know the ins and outs of what’s available, and see why the crew on one project chose replacement windows from Vetus.
