Marine drive vane steering system

In a marine drive for mounting in a boat,

• (A) an engine,
• (B) a steerable drive unit connected to said engine,
• (C) transom support means for attachment of said marine drive to the boat,
• (D) a steering arm fixed to said drive unit for steering said marine drive,
• (E) a lower gearbox attached to said drive unit,
• (F) a horizontal propeller shaft positioned in said gearbox,
• (G) a propeller fixed to said propeller shaft for rotation with said propeller shaft,
• (H) an anti-cavitation plate having a substantially horizontal surface positioned above said propeller,
• (I) a steering means connected to move said steering arm said steering means including a push-pull steering cable having an inner core supported in an outer casing,
• (J) a vane vertically positioned behind said propeller on a substantially vertical pivot shaft rotatably supported in said anti-cavitation plate,
• (K) vane rotating means connected to rotate said vane on said pivot shaft upon an initial movement of said steering means, said vane rotating means having an inner core supported by an outer casing, wherein the improvement comprises a steering system including:
• (a) a guide tube fixed to the end of the outer casing of said steering cable,
• (b) a link rod connecting between said steering arm and the inner core of said steering cable,
• (c) a guide means fixed with respect to said transom support means to guide the linear movement of said guide tube,
• (d) a limiting means for limiting the range of movement of said guide tube, and
• (e) restoring means to move said steerable drive unit from the extreme range of said range of movement of said steering arm.
