ZF Friedrichshafen AG, also known as ZF Group, and commonly abbreviated to ZF (“ZF” stands for “Zahnradfabrik” which means “Gear Factory”). ZF is a German car parts maker headquartered in Friedrichshafen, in the south-west German region of Baden-Württemberg.
Specialising in engineering, it is primarily known for its design, research and development, and manufacturing activities in the automotive industry. It is a worldwide supplier of driveline and chassis technology for cars and commercial vehicles, along with specialist plant equipment such as construction equipment. It is also involved in rail, marine, defence and aviation industries, as well as general industrial applications. ZF has 113 production locations in 26 countries with approximately 71,500 employees.
ZF Marine Transmissions is a subsidiary of the ZF Group ($14 billion in annual sales). ZF Marine is now the largest supplier of marine transmissions, propellers, surface drives, and controls in the world.
The company was founded in 1915 in Friedrichshafen, Germany by Ferdinand von Zeppelin, to produce gears for Zeppelins and other airships. Zeppelin was unable to otherwise obtain gears for his airships.
By 1919, ZF had moved into the automobile market, a move consolidated by the terms of the Treaty of Versailles. Some of the most important milestones that followed:
- 1921: Under a rampant inflation and investor fears, the company goes public as the Zahnradfabrik Friedrichshafen AG, with the Zeppelin Luftschiffbau GmbH holding 80% of the stock options, valued at 4 million Marks.
- 1929: A thriving auto industry warrants the series production of the innovative helical ZF Aphon transmission for cars and commercial vehicles
- 1944: On 3 August, the Zahnradfabrik was bombed by the Fifteenth Air Force.
- 1953: Market launch of the first fully synchronised transmission for commercial vehicles worldwide.
- 1961: Development of a fully automatic transmission for passenger cars. The 1960s sees ZF supplying transmissions to major German automakers (including DKW, Mercedes-Benz, Porsche and BMW) as well as Peugeot and Alfa Romeo.
- 1986: Start of USA transmission production in Gainesville, Georgia, for pickup trucks. ZF became a major supplier to Ford in the 1980s.
- 1995: ZF Acquires the Italian-based Hurth Marine Gear which continues to produce the smaller gears under the ZF name.
- 2001: ZF Acquires Mathers Marine Controls. Mathers Controls, introduced the industry’s first single lever control over 50 years ago, and has been the leader in the industry with electronic engine controls such as the MicroCommander system for marine vessels, yachts, and pleasure boats.
- 2013: ZF Opens Passenger Car Transmission Plant in the U.S.
- 2014: Acquires American auto parts manufacturer TRW Automotive for $13.5 billion.

Frequently Asked Questions
What oil is in my transmission?
Models 5 through 85 will primarily use automatic transmission fluid. Models 220 through 60000 will generally use SAE 30W monograde engine oil. Refer to ZF FIlter & Lubricant Cross Reference (PDF) from www.marinepartsexpress.com for specific instructions or contact ZF.
What is my oil capacity?
Capacity is listed on Spec Sheet for your model. Look under the dimensions table. Many models have the capacity right on the gear on the ZF data tag.
STANDARD CONFIGURATION (WITHOUT NAME EXTENSION)
- Reversing transmissions
- 3-Shaft configuration
- Vertical offset (input above output)
- Parallel offset
OTHER CONFIGURATIONS / MODEL DESIGNATIONS
|No Letter||Vertically Offset (input above output)|
|IV||Integral Vee-drive (flanged on to engine)|
|M||Mechanical clutch actuation|

Ratings apply to marine diesel engines at the indicated speeds. At other engine speeds, the respective power capacity (kW) of the transmission can be obtained by multiplying the Power/Speed ratio by the speed. Approximate conversion factors:
1 kW = 1.36 metric hp
1 kW = 1.34 U.S. hp (SAE)
1 U.S. hp = 1.014 metric hp
1 Nm = 0.74 lb.ft.
1 Kg = 0.454 lb
Ratings apply to right hand turning engines, i.e. engines having counterclockwise rotating flywheels when viewing the flywheel end of the engine. These ratings allow full power through forward and reverse gear trains, unless otherwise stated. Contact your nearest ZF Sales and Service office for ratings applicable to gas turbines, as well as left hand turning engines, and marine transmissions for large horsepower capacity engines. Ratings apply to marine transmissions currently in production or in development and are subject to change without prior notice.
NOTE: The maximum rated input power must not be exceeded (see respective ratings in the technical data sheets).

FROM Donald: "This is an awesome website. I found the information that I needed right away from one of the over 10,000 free articles that you provide as a public service. I'm surprised that so much if this site is free. But I still signed up so I could access the thousands of expanded pages, interesting articles, and dozens of valuable programs! The member's library of books, magazines and videos that I can view online is really terrific! I understand that you and your staff are all unpaid volunteers. Please keep up the good work. And I commend you for your plans to add another 10,000 free informative articles over the next year. I'm thrilled to support you in this endeavor with my small membership donation. Thanks again for all your hard work."
FROM Huey: "I agree with my Uncle, I too have found the articles to be very enlightening. They say that it will take about 50,000 articles to cover the full scope that they have envisioned for the website. They have over 10,000 articles so far and that's doing pretty well, but it could take several years to get the rest. I also noticed that many of the Main Topic Pages and some of the article pages are still in the rough draft stage. I guess that they will fill in as they can get volunteers to work on them. But what I can't figure out is why anyone would spend the time writing informative in depth articles just to give away free to this website for publication? What's in it for them?"
FROM Dewey: "Well Huey, to me It looks like most of the articles on this website are written by very informed people, like boating instructors, boat designers, boat builders, riggers, electricians, fitters, marine repair technicians and marine surveyors. Writing such articles helps establish them as knowledgeable professionals. After all, this website was originally created by a school for marine technicians and marine surveyors. The website is growing in content every day. They even had to move to a bigger, more powerful server on October 15, 2018 because the website's traffic has been growing exponentially."
FROM Louie: "I agree with everyone above. This site is quickly becoming the ultimate reference resource about every aspect of boats and ships for everyone from the beginning recreational boater to the seasoned professional mariner. I use the topic pages on the right sidebar to browse around the website. It's like a Junior Woodchucks' Guidebook for Boaters. Their Members' Library of over 300 popular and obscure books and over 200 magazine back issues that can be viewed online is fabulous. The Academy's magazine is especially informative. On top of that, there is the "Ask-An-Expert program for members where you can get an expert's answer to any of your boat questions. And a whole years membership is only $25. What a deal! I really love being part of this "Everything About Boats" community and help provide thousands of helpful articles free to the public. I think that I'll sit down right now and write an article about my experiences boating with my uncle."
FROM Scrooge: "You rave about this website like it was the best thing since sliced bread. Well, I think it stinks. Sure, it has a lot of good information for boaters, and they're adding more every day, but it will probably never be finished. Furthermore, I don't even own a boat. And I wouldn't have a boat even if someone gave me one. Boats are a waste of money and time and energy and money! They're just a hole in the water you pour money into. If you gave me a boat, I'd sell it quicker then you could say Baggywrinkle. Then I'd lock up the cash with all my other money so I could keep my eye on it and count it every day. Bah humbug."
FROM Daisy: "I'm just so glad that Donald got the boat so we and the boys could enjoy boating — together. And of course all of the girls, April, May, and June, love to be on the water too, especially when that is where the boys are. Oh poor Scrooge, boating is more fun then you could possibly imagine."
FROM Editor: "For those of you that have stayed with us this far, Thanks. You inspire us to keep working on this labor of love. We know that we have a lot more to do. Ultimately, we hope that we can help you enjoy the wonder filled world of boating as much as we do. We are all waiting to see what you have to say about this webpage article. And we assure you, your corrections, updates, additions and suggestions are welcomed. Let's work together on this." ♥
