Back in mid-July we held the 2025 Engine Performance Expo, our first 100% live event hosted by Rottler Manufacturing at their HQ in Kent, Washington.

It was an amazing 3 days with machining demos, presentations by Digital Metrology, Darin Morgan of BES Racing, Total Seal Piston Rings, and, of course, Rottler Manufacturing.

The full videos from the presentations are still in the works, but in the meantime check out these highlights from the event!

On this episode of Rottler Featured Series, join us in Friedheim, Missouri with Jeff Baldwin of Baldwin Racing Engines.

Baldwin Racing Engines opened back in 2002 as an automotive repair shop but quickly evolved in a full-service automotive and competition machine shop that works on everything from Japanese mini trucks up to Cat C15s and Cummins ISX engines.

Their entry into the performance engine world began back in 2003-04, but really opened up in 2005 when he built the championship-winning engines for Mark Todd for three years in a row. Since then, they’ve built a name for themselves in LS late model dirt track and derby engines winning multiple championships for drivers like Scott Bloomquist and Nick Hoffman.

Baldwin credits a lot of his success to the specialty machining services — blueprinting cam tunnels, lifter bores, surfacing, and other high precision work they do with their Rottler equipment, which includes the H85AX automatic hone and an F60 series multi-purpose machining center. He notes that the Rottler machines give them the ability to refine surface finish, the key to ring seal and drawing every ounce of power out of the engine they can. A big difference, especially in the two-barrel restricted engines where the rules strictly limit what they’re allowed to do.

Over the past two decades Baldwin Racing Engines has earned an unmatched reputation for engines that win championships, and we’re pleased that Rottler is there to help with the best equipment and technology the industry has to offer.

For this episode of the Rottler Featured Series we went to Middletown, Rhode Island to visit Toni Marine where they’ve been rebuilding Yamaha / Mercury outboard engines since 1958.

We met with owner Will Correia who told us how they came to exclusively remanufacture Yamaha outboard engines, getting into the engine overhaul business back in the 1990s. They can take an old engine, “basically junk,” in Will’s words, and make it like new again, fully warrantied and ready to run. Will explained to us that most people just want to sell an outboard boat owner a new engine, which can cost $30,000 or more. Remanufacturing an old engine and brining it back to new condition is a great costs savings for his customers.

One of the big reasons for Toni Marine’s success is that they only use the best tooling and equipment, which includes half a dozen Rottler engine rebuilding machines. In Will’s words, “if you’re going to buy something, buy the best,” and that means Rottler.

The newest piece of Rottler equipment on the shop floor is an H8A automatic hone, which Will refers to as a “robot employee” because it runs itself and delivers a better finish than any human can. He told us he was worried at first about these machines being too complicated to run, but he’s had no issues. “Anyone can learn to run one in 20 minutes,” he said. “I’m 70 years old, and I can run [a Rottler] machine while I’m on the phone. It’s not an exaggeration, it’s that good,” he added.

We love to hear words like that from our customers, because it motivates our team to keep innovating and building the best engine-focused CNC machines in the industry.
Check out Toni Marine’s story in the video, and, if you’re in the market for the best-rebuilt outboard motor money can buy, give their website a visit!
