What our customers are saying...

“After 31 years, 13,000 open-ocean miles plus countless day-sails and overnighters, my Norscot Shaft Seal is still going strong. Total maintenance during those 31 years? I’ve topped off the ATF twice. No leaks. I highly recommend the Norscot Shaft Seal. No reservations whatsoever.”

~ B.B., 1981 Tatoosh 42


“I have more than 4500 hours on my Eastbay 38…all with the same seals aboard. Great product- thanks for inventing it!”

~ Tom, M/V Jo


“I’ve used Norscot for 20 years- never have to worry about salt water in the engine room. It’s easy to maintain. I still love it after 20 years.”

~ Tony, Owner of 1991 Tollycraft Sport Cruiser 30 for 20 years


“A simple design, yet a burly system. I sleep well at night knowing I have a Norscot.”

~ Paul, Owner of 1976 Islander 28′ for 18 years


“I installed new seals in my boat after having the shaft out for repairs. I put 400 hrs per year on the boat and I might go through a 1/4 cup per year. All good in western Canada!”
