Marine Engines

Mitsubishi Marine Engines cover from 429hp to 1,260hp and meet all the current EPA regulations. Our marine engines offer a variety of applications for the marine market.

Light Duty Application

  • Main Use: Pleasure Boats, Yachts, Patrol Boats, Fire Fighting Boats
  • Annual Engine Running Hours: Up to 3000hrs
  • Overhaul Period: 8,000 hrs or 3 years

Medium Duty Application

  • Main Use: Bay Area Tug Boats, Working Boats, Passenger Boats, Ferry Boats
  • Annual Engine Running Hours: Up to 6000hrs
  • Overhaul Period: 8,000~12,000hrs

Heavy Duty Application

  • Main Use: Fishing Boats,Cargo Boats,Pusher Boats
  • Annual Engine Running Hours: 6000~8000hrs
  • Overhaul Period: 12,000~16,000hrs

Mitsubishi engines have a worldwide reputation for reliability, fuel economy and long life and their long strokeand low compression reduces engine stress. Mitsubishi marine engines give you an average of 25% more iron than their competition. An engine with greater displacement is stronger. Its larger mass provides greater inner strength for higher reliability. Service friendly design saves maintenance cost and shortens machine downtime.

If you are looking for an engine that you can rely on day in and day out, Mitsubishi is here for you. Contact one of our distributors located within the maps on our distribution tab above. Our accredited representatives will serve you with the engine sales, parts or service you need.

What we have accomplished so far.
Anchors Aweigh Academy and its EverythingAboutBoats.org website.

  • Published over 50,000 website pages about boats and boating, bringing us closer to reaching our goal of becoming "The ultimate reference resource about boats and ships for everyone from the beginning recreational boater to the seasoned professional mariner!"
  • Published over 300 website main topic webpages, many with full articles on the topic. See our Website Contents or the Right Sidebar for the listing of the main topic pages.
  • Published over 9,000 marine vendor webpages, all with their contact information, most with a description of their products and services, many with product documentation, specifications and independent reviews. (incl.: Boat designers, boat building tools, material and equipment manufacturers and suppliers, boat builders and dealers, yacht brokers, marine surveyors, boat insurers, boat transporters, skippers and crews, boatyards and marinas, yacht clubs, boat rentals and yacht charters, boating, seamanship and maritime schools, marine law attorneys and expert witnesses, boat refitters and repairers, book authors, magazine publishers, video producers, and website creators)
  • Acquired over 120,000 pages of product documentation including Catalogs, Brochures, SpecSheets, Pictures, Serial Number Guides, Installation Manuals, OpManuals, Parts Catalogs, Parts Bulletins, Shop Manuals, Wiring Diagrams, Service Bulletins, and Recalls. And have made all viewable to Academy Members through our EAB website eLibrary.
  • Acquired over 1,200 books and magazine back issues in our academy library and so far have made over 700 viewable to Academy Members through our EAB website eLibrary.
  • Published over 500 DIY How-To articles about boat design, construction, inspection, operation, maintenance, troubleshooting and repair. We are working hard to do more.

We are currently formatting and polishing the Anchors Aweigh Academy online and hands-on courses. Our Marine Surveying course has proven to be excellent for both the beginner and the seasoned surveyor, and especially helpful to the Do-It-Yourselfer.

General Comments About the Website

FROM Donald: "This is an awesome website. I found the information that I needed right away from one of the over 20,000 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 100,000 articles to cover the full scope that they have envisioned for the website. They have over 20,000 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 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 Scrooge: "After seeing how much fun you all have on the water together, I regret that I didn't have that much fun when I was young. I've had a change of heart, and I'm giving each of you a Lifetime Academy Membership."

FROM Editor: "For those of you that have stayed with us this far, many thanks, and we hope that you found this little narrative informative. Your faithful support inspires us to keep working on this phenomenal website. 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.
