Of the many outboard model boats pictured on their website, most are equipped with a Yamaha outboard engine. THUNDER JET describe themselves as follows:
Established in Clarkston, Washington, in 1981, Thunder Jet began with founder Darrell Mills heading up sales, his wife Liana doing the books, and employing one welder, rig tech, and painter. In their first year they produced just five boats, but that is all it took and Thunder Jet was the latest industry buzz.
Thirty years and over 6,000 boats later, Thunder Jet now holds the position as one of the most successful aluminum boating companies to ever exist, a direct result of their superior product and continued efforts improve and adapt to the ever changing boating community’s needs.
Today Thunder Jet is the most advanced heavy gauge aluminum boat builder in North America. By utilizing and investing in the newest and best in equipment, people, and practices, Thunder Jet Boats are the highest quality, best finished, and best valued boats available today. Our commitment is to continue finding and investing in better ways to make high quality aluminum boats affordable, fuel efficient, resilient, and appealing, so that more people can enjoy the experiences that boating can offer.
Brunswick's press release from July 5, 2016 explains their motivation for this acquisition. Because Brunswick is a publicly traded company, I would expect they will eventually disclose to their investors the price of this acquisition in some SEC filing, although their comment that his acquisition "will have minimal impact on earnings" perhaps foreshadows they'll keep the price a secret.
