摘要： The invention relates to a steering arrangement for boats equipped with inboard-outboard drive (10). The gearbox (22) of the drive is arranged so as not to be horizontally pivotal in relation to the stern (12) of the boat, while the underwater housing (26) of the drive is horizontally pivotal in relation to the gearbox (22). For rotating the underwater housing in relation to the gearbox, a steering gear (44-56) acts which comprises a toothed segment (56). Hereby a total steering angle of up to 180.degree. can be obtained.

摘要： A tuned exhaust gas relief system for marine propulsion systems, for example an outboard motor, includes a lower drive shaft housing coupled to a two stroke engine by a pair of intermediate stacked exhaust extension plates. The housing directs the exhaust gas downwardly to a through-the-hub exhaust propeller for exit therethrough. With the unit in reverse or idling, exhaust gases are trapped within the housing. A pair of tuned exhaust relief passageways may be formed by cavities in the mating faces of the two extension plates with a pair of inlet openings in the lower wall of the bottom plate. A baffle member may overlie the inlet openings. The passageways define constant cross-sectional area channels which terminate in exhaust openings in the rear wall of the drive shaft housing. A resonant cavity, which may be integrally formed by mating recesses in the opposed faces of the extension plates, is in close spaced relation to each idle exhaust passageway. Connecting openings are distributed along the length of the common wall between the cavity and passageway. An exhaust housing within the drive shaft housing forms an exhaust expansion chamber of high acoustical impedance between the lower ends of the exhaust pipe means and the upper wall extension plate assembly. The idle exhaust passageways have a low acoustical impedance, so that the acoustical impedance mismatch between the chamber and the passageways attenuates the high frequency sounds. The idle exhaust passageways may transmit the half wave frequency and even multiplies thereof. The resonator cavity is selected to attenuate the particular half wave frequency, or an even multiple thereof, which because of physical space requirements may be present and not attenuated by the idle exhaust passageway means.

摘要： Provided is a trimming and stabilizing arrangement for motor-driven vessels of the type in which the engine of the vessel is placed in the stern thereof and comprises either an outboard engine or an inboard engine with an outboard drive, wherein the propeller driven by the engine is located beneath a holding device in the form of a fin, serving as a stabilizer, and wherein the steering of the vessel is effected by pivoting the propeller about a vertical axis. A plate is arranged to coact with the fin and extends over the propeller and beyond the propeller sternwardly of the vessel. The plate has a downwardly facing planar surface, the edges of which in the direction of movement of the vessel are curved downwardly. The holding device and plate comprise at least two parts, one of which co-acts with and embraces the motor leg of the engine immediately above the propeller, and the other part comprises a planar plate co-acting with the holding device via attachment apparatus.

摘要： An elongated tubular handle is secured to the upper head of an electric trolling motor. A steering push-pull cable and electrical cables for guided and protected movement during the raising of the motor. The handle is formed with rectangular cross-section and of a relatively stiff, rubber and tapers from a heavy, stable end connected to the head to a relatively thin section outer grip end. The handle extends inwardly into the boat for convenient pulling directly backwardly on the outer end of the handle to cause the motor to pivot upwardly and inwardly into the boat without kinking of the cables and without twisting of the handle in the operator's hand.

摘要： A steering structure for a ship propelling device includes: a support member for supporting the body of the ship propelling device on a hull; a universal joint for connecting between a drive shaft connected to a drive source and an input shaft of the ship propelling device; a vertically driving means adapted to cause the body to vertically pivot about a pivot shaft; and a turning driving means adapted to cause the body to pivot about an axis orthogonal to the axis of the pivot shaft. The vertically driving means and the body are connected together through a link mechanism. Such arrangement makes it possible to turn the whole of the ship propelling device independently of any vertical movement thereof, contributing to reduction of the production cost and a stable steering operation of the propelling device.
