Defective Yamaha Boat Motor Lawsuit

Consumers who have purchased first generation (2002-2004) four stroke outboard motors and reported a rapid buildup of corrosion on internal parts, as well as dry exhaust corrosion may have legal recourse to collect compensation for the cost of repairs and other damages. It has been alleged that the company’s first-generation F-Series four-stroke outboard motors (model years 2000 – 2005) contain a serious defect that allows the exhaust passages to corrode and pit severely, ultimately resulting in premature engine problems and failure.

If you have experienced problems with this outboard motor, you may be able to participate in a class action lawsuit against Yamaha. To learn more about your legal rights, please contact us for a free case review form with details on your motor problems.

Yamaha Boat Motors Defect

Consumers claim that despite proper service and maintenance, certain first generation outboard motors have corroded to a point of impaired function and necessitated significant repairs or replacement. It is believed that premature engine failure and related issues are linked to a manufacturing or design defect in the coating of the aluminum exhaust component that allows hot gases to corrode the exhaust passages, which in turn can lead to holes in the passages and can eventually cause a loss of horsepower, smoking and engine failure.

Unfortunately for consumers, this alleged defect cannot be readily discovered and is hidden within the engine. Consumers will only see the effect of the alleged defect well after the corrosion has advanced.

The Yamaha Warranty Has Expired

It has been alleged that the corrosion can occur in as little as 200 hours of usage and engine problems are discovered between 500 and 700 hours of operating time. Because recreational boaters will typically use these engines for less than 100 hours per year, it is likely that the engine will fail after Yamaha’s three-year extended warranty has expired, leaving the consumer to front the bill for repairs which could cost thousands.

Yamaha has changed the coating in newer outboard motors, and the company created a kit for the models in question, but it costs $650, plus thousands more to implement. To date, Yamaha has not issued a recall.

A class action lawsuit is alleging that proper engineering tests would have revealed the issue with the exhaust components and that a proper coating would have better protected the aluminum and offered more resistance to the hot exhaust gases emitted by the motor.
