Description

This powerhouse V6 300?hp outboard combines Yamaha’s legacy of reliability with modern features like digital control capability, optional bolt-on electric steering, and thrust-enhancing reverse exhaust. At ~562?lbs and tuned for a 5,000-6,000?rpm powerband, it’s ideal for offshore or high-performance coastal rigs. With intelligent engineering, such as the TotalTilt™ feature and clean routing of exhaust in reverse, this motor truly delivers usability alongside muscle. Ask us how we rig this beast or compare it to the XSB integrated-steering variant.
