  • Marine dual propeller lower bore drive assembly
    Patent number: 5462463
    Abstract: A marine drive (10, 310) has two counter-rotating propellers (12 and 14, 312 and 314). Inner and outer concentric counter-rotating propeller shafts (40 and 42, 340 and 338) are supported by a spool (38, 336) in the lower horizontal bore (28, 328). Passages are provided in the housing for communicating lubrication and/or exhaust with the horizontal bore. Locking structure (50, 404) holds the driven gears and bearings in place in the lower horizontal bore.
    Type: Grant
    Filed: November 21, 1994
    Date of Patent: October 31, 1995
    Assignee: Brunswick Corporation

  • Marine drive with dual propeller exhaust and lubrication
    Patent number: 5352141
    Abstract: A marine drive (10) has a spool (36) positioned in the lower horizonal bore (28) and supporting a dual propeller shaft assembly (38, 40). An exhaust passage (130) includes a passage (132) in the drive housing (26) communicating with the horizontal bore (28) at the spool (36), and a spool exhaust passage (134) passing exhaust rearwardly through the spool to the propeller through-hub exhaust passages (136, 138), providing through-hub exhaust through dual propellers (12, 14). An oil passage (152) in the housing (26) communicates with the horizontal bore (28) forwardly of the exhaust passage (132) and lubricates the dual propeller shaft assembly.
