What our customers are saying...

“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

“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’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

“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 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!”

Bill Higgs

“It doesn’t drip or leak. I’ve had the boat for 18 years, put 1500 hours on it during that time without the need to replace the seals. Couldn’t ask for anything better!”

Rick, Owner of 1995 Bayliner 33′ for 18 years

In a word, Norscot is terrific. I highly endorse this product. It should be original equipment on all inboard power boats.

Richard, Owner of 34' Sea Ray

This year we took a 3-week cruise to the Broughton Sound area in BC. This involved extensive running to get there and return. It was a pleasure not to have to head for the bilge to tighten the old packing glands after each run. We continue to have outstanding results with the seals!

Rob, Owner of 36' Tollycraft

Why Norscot is the only choice

At the heart of the Norscot is a marine-grade bronze housing. Inside the housing, lip-type oil seals form a leak-free, press-fit with excellent retention of light oil. The kit includes our own custom aluminum installation or 'transfer’ tool to protect the lip-type seals during installation.

Our unique system is the only dripless shaft seal on the market using Transmission Fluid (ATF) for lubricant contained in a specially designed and molded reservoir bottle, creating an independent entity unlike water-injected dripless systems.  

Norscot’s overall simple and tight design creates a shaft seal that is long-lasting, safe, reliable, with low maintenance.

So, no matter what happens with your engine or the condition of the water you're in, you'll appreciate the unmatched performance of The Norscot Shaft Seal and cruise worry-free for years to come.
