About Us

Our Service Area

We generally service from Boston to Provincetown to Newport, but we do travel further as needed.

Windward Power Systems is a family owned and operated business, founded by father & son team Jim and Nathan Tynan in June, 2006. We sell, repair, and service marine diesel engines and parts at our facility in Fairhaven, Massachusetts. We founded our business on some very simple principles‒ offering only the highest quality products and providing exceptional service to support those products.

Committed To Service

We will never sell a product that we can’t service. Windward Power is dedicated to giving our customers everything they need in one place, and we carry several other product lines outside of marine diesel engines that compliment our customers’ needs.

Please take a look around our website and feel free to contact us if you have any questions or if we can be of service. We make every effort to accommodate requests and take the time to solve your problems, so even if we don’t have the product or service you’re looking for, we’d be more than happy to refer you to someone who does. We looking forward to hearing from you.

"I would like to take a moment and thank you again for your help in the repower job this year. I have pushed harder fishing this year than I have in a long time..."

"Just wanted to let you know how much I appreciated your, and your company's professionalism this spring. I've dealt with a lot of diesel mechanics over the years."

"Thanks again for all of the work you guys did this past year. We all appreciate it, especially the guys who are off shore with an engine we know was built by the best."

"Nate, thank you for all your hard work and insights, it was very helpful and I learned a lot; specifically what mechanical issues to look for...I was very impressed..."
