Document Type and Number:
Japanese Patent JP2683693
Kind Code:
B2
Abstract:
A tilting device for a tiltable outboard drive unit on a marine vessel which prevents the drive unit, when in the tilted-down position, from freely moving toward the tilted-up position during normal operation. The tilting device includes a tilt cylinder device having a bypass valve, and is arranged so that the bypass valve of the tilt cylinder device is automatically closed when the drive unit is in the tilted-up position. Thereafter, when the drive unit is moved to the tilted-down position the bypass valve remains closed, thereby preventing the drive unit from freely moving toward the tilted-up position during normal operation.
