Abstract: A hydraulic steering apparatus 1 has a substantially bow-shaped frame 2, which includes a pair of end portions 2a bent forward. A piston rod 3 is supported by and between the end portions 2a. A hydraulic cylinder 5 is supported by the piston rod 3 slidably along it. The frame 2 also includes a middle portion 2A, which has bolt holes 2B cut through it. Bolts 11 extend through the bolt holes 2B and engage with the front end of the swivel bracket 41 of an outboard engine 40 to fix the frame 2 to the bracket. The cylinder 5 is linked to the front end of the steering lever 46 of the engine 40 by a steering link 7.

Abstract: A tilt tube 21 extends along a horizontal tilt axis B. A steering hydraulic cylinder 8 slides along a piston rod 7, which extends in parallel with the tilt axis B. An eccentric link shaft 6 is positioned between the tilt tube 21 and piston rod 7 and extends in parallel with the tilt axis B. A pair of linking means 4 supports the tilt tube 21, link shaft 6 and piston rod 7. The distance L0 between the tilt tube 21 and piston rod 7 is shorter than the sum of the distance L1 between the tilt tube 21 and the link shaft 6 and the distance L2 between the link shaft 6 and the piston rod 7.
