A manual hydraulic steering apparatus is provided for a vessel, which is fitted with a dashboard D having a larger hole D 1 and a smaller hole D 2 both cut through it. The steering apparatus includes a tilting mechanism 1 positioned on one side of the dashboard D and a hydraulic pump 51 positioned on the other side. The tilting mechanism 1 includes a mounting plate 3 in contact with the dashboard D. A tilt housing 2 is fixed to the mounting plate 3 and has an oil feeding tank 11 formed in an upper portion thereof. The feeding tank 11 has an oil feeding port 12 a, in which an oil plug 12 is fitted removably. A semispherical shell 4 is supported turnably in all directions by the tilt housing 2 . A steering shaft 5 is supported rotatably by the semispherical shell 4 . The hydraulic pump 51 includes a pump casing 52 , which has a mounting part 52 b extending into the larger hole D 1 of the dashboard D. The mounting plate 3 of the tilting mechanism 1 is fixed to the mounting part 52 b of the pump casing 52 . The hydraulic pump 51 has a driving shaft 53 extending through the mounting part 52b of the pump casing 52 and the mounting plate 3 of the tilt housing 2 . The steering shaft 5 is coupled to the driving shaft 53 rotatably with the driving shaft and tiltably on a horizontal axis perpendicular to the driving shaft. An oil feeding pipe 13 extends through the smaller hole D 2 of the dashboard D and communicates with the oil feeding tank 11 and the oil tank 54 of the hydraulic pump 51.
