ABSTRACT:
Front and rear lifts (10) of the present invention are secured to the platform (14) of a pontoon boat (12) intermediate the flotation units (20). A U-shaped lift module (32) including first and second legs (36) extending from a central spindle (34) is pivoted about pivot pins (64) relative to first and second mounts (26) by actuators (74) extending between the mounts (26) and the legs (36) between a retracted position generally parallel to and adjacent the platform (14) and a lift position extending at an acute angle to the platform (14). The legs (36) each include first and second C-shaped posts (38) extending from the central spindle (34) and slideably received in first and second tubes (42). Bolts (52) extend through an aperture formed in the outer side wall (46) of the tubes (42), extend through one of a series apertures (40) formed in the C-shaped posts (38), and are threaded into sleeves (48) secured to the inner side walls (44) of the tubes (42) by bolts (50). The actuators (74) are pivotally received between the first and second posts (38) and tubes (42). A ground support pad (54) is pivotally mounted by U-shaped straps (62) to the central spindle (34). Pivot bushings (66) are secured in the tubes (42) by deforming the side walls (44, 46) and slideably receive the pivot pins (64) between the legs (36) and the mounts (26) and between the legs (36) and the actuators (74).
