300HP Models

Yamaha’s 300-horsepower V6 and V8 outboards are perhaps the most trusted in their categories, delivering class-leading reliability, strong performance, and excellent fuel efficiency.

But despite their legendary reliability status, these outboards aren’t bulletproof. Besides, they are not exactly cheap to maintain, especially if you rely solely on your local Yamaha dealer, which may charge you a pretty penny for a job you could very well do on your own.

And since proper maintenance is key to reliability, skipping on services is definitely out of the question here. Fortunately, you can significantly reduce your motor’s maintenance costs using one of our Yamaha 300 HP outboard repair manuals.

Indeed, our service and repair manuals contain everything you need to maintain and repair your outboard, including step-by-step instructions, clear images, diagrams, exploded-view illustrations, and torque specs.

Moreover, since all of our Yamaha 300 HP repair manuals come in digital form, you won’t waste a single minute browsing a bulky paperbound manual anymore! Instead, you can save them on your smartphone, tablet, or laptop, quickly find any procedure you need with just a quick search, and even carry all your repair manuals with you the next time you leave for a short ride out at sea!
