History of Tohatsu Outboards

Tohatsu is Japan’s oldest outboard manufacturer. Tohatsu’s first outboard engine was built in 1956, and from the beginning were found on the belief of building an engine that is dependable and adaptable to different uses. Over the last 60 years the outboards have served a variety of different industries including rafting on the Colorado River, commercial fishing, marine transport, competition, and recreation. To keep up with the competition and customer demands, products have been developed and researched with know-how and advanced technology. Tohatsu built its first 4-stroke engine in 1998, its first TLDI(Two-Stroke, Low Presser, Direct, Injection) clean burning two stroke engine in 2000, and introduced the Everrun series aimed at commercial industries in 2011. Tohatsu was the first to offer a battery-less EFI system in the 30 HP that provides quick throttle response and very smooth rides on the water. This is the engine that Colorado River & Trail Expeditions uses on the Colorado River in Grand Canyon. Prior to manufacturing outboards “Takata Motor Research Institute,” which was founded in 1922 built train carriages, high-speed portable engine generators, motorcycles, and radio controlled generators.


Tohatsu Marine Corporation was set up in 1988 as joint venture with Brunswick Corporation, USA. Mercury Marine is a division of Brunswick Corporation and many of the smaller Mercury Outboards are just rebranded Tohatsu Engines. In addition, the entire line of Nissan outboards are rebranded Tohatsus. More recently Evinrude/Bombardier released a press release saying that they would be rebranding small Tohatsu engines for their line, and Tohatsu has begun using larger Honda outboards(60, 75, 90, 115, 150, 200, 225 and 250 hp models) to fill out their line-up. All in all Tohatsu seems to have a pretty amazing line of engines.

Tohatsu’s USA headquarters is located in Carrollton, Texas, a suburb of Dallas. All of Tohatsu’s outboard engines are produced in Japan. A new state of the art warehouse was built in central Japan in 2005 that has 370,000 square feet of space and a production capacity of over 200,000 outboards per year.


Colorado River & Trail Expeditions was the first to use the Tohatsu four stroke 30 hp outboard engine for rafting the Grand Canyon in 2002. We have been impressed with the Tohatsu from that first trip and continue to utilize the Tohatsu 30 hp which over time has evolved from a carbureted model to an electronic fuel injected model or EFI. The 30 HP weighs about 158 lbs in its basic form which is very competitive with Honda and other manufacturers. The engine does a great job in the rapids and heat of Grand Canyon and very rarely has been swapped out for the spare because of a mechanical problem.

It is always fun to hear questions about the outboard engines on river trips. In general our guests are pretty amazed with how quiet the motors are. Many of our guests also like to tell about their Tohatsu at home that “just keeps running.”


We specialize in the Tohatsu 30 Horsepower outboard engine. We know a lot about these engines and sell them new and used. If you are looking to buy an engine, or have a question about the Tohatsu 30 comment below or send us an e-mail with subject line Tohatsu 30 to crate@crateinc.com.

The Colorado River below Glen Canyon Dam flows through the lower reaches of Glen Canyon on its way to Lees Ferry , forming one of the most studied and discussed stretches of river in the American Southwest. Released from the base of the dam, the water is typically clear and tightly controlled. In recent years, however, lower water levels in Lake Powell have caused releases to come from shallower depths, warming the river compared to past decades and changing the conditions downstream. This reach is calm and approachable, making it a popular destination for kayaking, rafting, fishing, and flatwater exploration. Visitors often take time to linger along the banks, explore side canyons, and pull over at small beaches and alcoves—experiencing the river at an unhurried pace that encourages observation and learning.  Quick facts about this stretch of river naturally help frame why it matters:

The Dirty Devil River joins the Colorado River at River Mile 169.5. John Wesley Powell camped at this confluence on July 28, 1869, describing the tributary as extremely muddy and foul-smelling. Jack Sumner later named it the Dirty Devil. The Dirty Devil is formed by the confluence of Muddy Creek and the Fremont River near present-day Hanksville, Utah. The Fremont River originates at Fish Lake and flows along the Waterpocket Fold through Capitol Reef National Park. Muddy Creek drains the San Rafael Swell. Historic Context — Powell’s Expeditions: Powell’s 1869 expedition recorded the Dirty Devil as both a geographic reference and a warning. In his later expeditions of 1871–72, Powell returned with improved boats and a scientific mandate. Tributaries such as the Dirty Devil became fixed reference points for mapping and geologic observation. Powell’s journals note the heavy silt load and poor water quality here, and his party avoided using the Dirty Devil as a water source when possible.
