Bracket unit
Upper mount
This model is the first Yamaha large outboard motor to use a layout with the vibration-isolation upper
mounts positioned on the outside of the upper case.
The installation location of the upper mounts has been changed from being secured inside the exhaust
guide to being secured to the left and right sides of the upper case. The upper mounts are positioned
at a wider pitch and slightly lower toward the rear of the outboard motor compared to previous mod-
els.
As a result, the height of the outboard motor is minimized and the full tilt-up angle is increased. This
helps to prevent the lower unit from being submerged when the outboard motor is tilted up while the
boat is moored.
The upper mounts are also easier to replace and have a lighter weight.
