Sleipner Motor AS
The factory area in the city centre of Fredrikstad, Norway.


Sleipner was founded in 1908 and employees today about 140 dedicated employees throughout the main office and factory in Norway and  sales offices in the UK, Germany, Denmark, Sweden and Finland. The main Sleipner products for the first 70 years was marine engines and propeller equipment. The Sleipner engines were very popular in Norway and many Norwegians has a relationship to these old charming engines, either themselves, or through their father, grandfather or even great-grandfather. The engines was known to be almost unbreakable and some actually still runs today.


The Quality Legacy

Sleipner has always been known for their uncompromised level of quality. Back in the old days, Sleipner was particularly proud of being one of the few manufacturers at that time with their own foundry. The sentiment was to keep production in-house to be able to obtain the necessary level of quality. Still, this is our sentiment, and today, we are equally proud of our modern factory lines with modern High-End CNC benches. With our dedicated focus on quality and control, our factory is ISO 9001 approved by the DNV GL. But, equally important as any certifications, is the people who actually manufacture the products. Every single of our employees is trained to ensure an absolute level of quality before any product ever leave our assembly lines. We work hard to make sure that Sleipner and the Side-Power brand will still be closely associated with exceptional quality in another 100 years as well!


A world leading manufacturer

At Sleipner, a huge number of the employees are dedicated boaters themselves. By spending time at sea, in sometimes less than ideal conditions, we have surely learned the absolute dependency you have to your vessel and the on-board equipment. With our substantial industry legacy in mind, we still strive to engineer and manufacture products you can rely on. To us, the fact that an overwhelming number of the world's leading boat builders choose Side-Power in their precious vessels, tells us that we are on the right track. The Side-Power thruster range is clearly the leading and most innovative thruster brand in the world in our segment today. 


Worldwide sales and service

Except for our own sales and service organisations in Norway, UK, Germany, Denmark, Sweden and Denmark, you will find a worldwide network of distributors with their own network of dealers and service personnel.

When choosing a Sleipner product, you choose products that are invented, engineered and manufactured by boaters - for boaters!
