A marine outboard drive unit (10) includes a two-cycle internal combustion engine (14), an oil storage tank (30) storing lubricating oil for the engine, and an assembly (44) mounted to the tank and extending into the tank for drawing oil from the tank and indicating the amount of oil in the tank. The assembly includes a collar (60) mounted to the tank in a top opening (42) and having first and second tubular portions (62, 64) extending integrally downwardly therefrom. The first tubular portion (62) is connected through a flexible coupling (80) to a lower tubular portion (78) formed on the outer surface of a cup member (74) mounted to the second tubular portion (64). The second tubular portion (64) retains an annular float member (66) and magnet (112) therearound in the annular space (76) between the second tubular portion (64) and the cup member (74). The second tubular portion (64) is hollow and houses and isolates a pair of electric wires and a reed switch (102) magnetically actuated by the float (66) and magnet (112).
