- 7. The apparatus of claim 1 wherein the housing is transparent.
- 8. The apparatus of claim 1 further comprising a bumper receiving slot configured to receive a bumper therein, and wherein the bumper is formed of a shock absorbent material.
- 9. A tilt-trim subsystem assembly affixed to an outdrive of a stern drive supported by a gimbal unit and configured to rotate about a predetermined axis to impart a desired trim or tilt to the drive system, the tilt-trim assembly having one respective end thereof configured to pivotally receive one anchor pin supported by the outdrive, the assembly including:at least one cylinder having one end thereof pivotally connected to another anchor pin such that when the at least one cylinder is actuated, the outdrive and the tilt-trim subsystem assembly are jointly rotated about the predetermined axis; a hydraulic circuit for actuating the at least one cylinder therein; a housing having a lower end; and a base for receiving the housing, wherein the base is sealingly connected to a flange extending at the lower end of the housing to prevent entry of moisture therethrough.
- 10. The tilt-trim subsystem assembly of claim 9 further comprising a bumper attached to a rearward end of the housing, and wherein the bumper is formed of a shock absorbing material.
- 11. The tilt-trim subsystem assembly of claim 10 wherein the housing has one end having a general U-shape to allow the housing to slide over the outdrive and another end that is closed.
- 12. The tilt-trim subsystem assembly of claim 9 wherein the housing is formed of a lightweight, corrosion resistant material.
- 13. The tilt-trim subsystem assembly of claim 9 wherein the housing includes a forward section having an interface edge configured to match a corresponding interface of a gimbal housing assembly.
- 14. The tilt-trim subsystem assembly of claim 9 wherein the housing is configured to be quickly mountable and quickly detachable to provide easy access to components shielded by the housing.
- 15. The tilt-trim subsystem assembly of claim 9 wherein the housing is configured to visibly shield components of the outdrive from an observer.
- 16. The tilt-trim subsystem assembly of claim 9 wherein the housing is formed of a translucent material.
- 17. The tilt-trim subsystem assembly of claim 9 incorporated into a stern drive system mounted on a boat.
- 18. A stern drive system having an outdrive generally disposed downstream relative to water flow aft a transom of a boat, the outdrive configured to be rotated about a generally horizontal axis to impart a desired trim or tilt to the drive system comprising:a gimbal unit configured to pivotally receive a first anchor pin; a tilt-trim assembly affixed to the outdrive, the tilt-trim assembly having one respective end thereof configured to pivotally receive a second anchor pin supported by the outdrive, the assembly including at least one cylinder having one end thereof connected to the first anchor pin so that when the at least one cylinder is actuated, the outdrive and the tilt-trim assembly are rotated about the generally horizontal axis, the assembly further including a circuit coupled to actuate the at least one cylinder therein; and a housing configured to shield the tilt-trim assembly, the outdrive configured within a footprint of the housing to avoid resistance to water flow.
- 19. The stern drive system of claim 18 wherein the housing includes a flange extending inwardly along a lower end of the housing.
- 20. The stern drive system of claim 19 wherein the tilt-trim assembly has a base attached to a lower end of the tilt-trim assembly configured to receive the housing flange.
- 21. The stern drive system of claim 18 wherein the housing includes a bumper receiving slot configured to receive a bumper attached to a rearward end of the housing.
- 22. The stern drive system of claim 18 further comprising a plurality of pliable fasteners configured to fasten the housing to the outdrive through a plurality of corresponding openings disposed at a base and a flange respectively.
- 23. The drive system of claim 18 further comprising a forward section of the housing having an interface edge configured to interface with the gimbal unit.
- 24. A kit configured to be affixed to an outdrive of a stern drive system supported by a gimbal unit and configured to rotate together with the outdrive to impart a desired trim or tilt to the drive system, the kit comprising:a base mountable to a lower end of a tilt-trim assembly; and a housing connectable to the base to sealingly enclose components of the outdrive.
- 25. The kit of claim 24 wherein the housing includes a flange inwardly extending along a lower end of the housing.
- 26. The kit of claim 24 wherein the housing includes a bumper receiving slot configured to receive a bumper attachable to a rearward end of the housing.
- 27. The kit of claim 24 further comprising a plurality of fasteners configured to fasten the housing to the assembly through a plurality of corresponding openings disposed in the base and flange respectively.
- 28. The kit of claim 24 wherein a forward section of the housing includes an interface edge configured to interface with a gimbal housing assembly.
- 29. A method of shielding a tilt-trim assembly of an outdrive the method comprising the steps of:positioning the tilt-trim assembly within a footprint of a base of an outdrive; forming a housing to include a semi-circular configuration with an inwardly directed flange at a lower end of the semi-circular configuration; and connecting the flange of the housing to the base of the outdrive thereby enclosing the outdrive within the housing.
- 30. The method of claim 29 further comprising the step of connecting a forward section of the housing to a corresponding section of a gimbal housing assembly.
- 31. The method of claim 29 further comprising the step of sealingly enclosing the tilt trim assembly from an external environment.
- 32. The apparatus of claim 1 wherein the base includes a forward end, a rearward end, and a pair of sides and wherein only the rearward end and the pair of sides engage the flange of the housing.
