UNDERWATEREQUIPMENT(Inboards)
Avoid runningagroundorstrikinga(submerged)
object. Serious damage to the engine(s) or in-
board underwater gear can result and the boat
cantakeonwater. Intheeventofsuchanoccur-
rence, proceed at low speed to the nearest ser-
vice facility and have an immediate inspection
made of the prop shafts and struts before further
use of the craft. Keep all life saving devices at
hand while driving to a dock area. If the boat
cannot be immediately removed from the water,
thoroughly inspect the bilge area for leaks so
that the boat does not sink while moored.

tion on stern drives.
A. Shaft Log
The shaft log allows the propeller shaft to extend and
rotate through the hull with only limited water leakage
occurring. Minor dripping may occur and is not abnormal
during operation. See Figure E2 & E3.
C. Inboard V-drives
Onthe V-drivepropulsionsystemof the inboards,allshift-
ing and gearing components are installed inside of the
hull, only the propeller shafts and associated equipment
are under water. The V-drive system has the engine
mounted in the extreme stern of the boat with the output
shaftfacingforward. Atransmissionwhichperformsshift-
ingfunctionsismounteddirectlyontotheengine. AV-drive
reduction gearbox is mounted directly to the transmis-
sion. The prop shaft is then connected to the V-drive
output coupling. See Figure E2.
Proper performance of the shaft seal is directly depen-
dent upon correct propeller shaft alignment. Propeller
damage, a bent strut or shaft, or abnormal wear, settling,
etc., are common reasons for misalignment. Therefore,
periodically have the shaft alignment checked and have
adjustments made when necessary.
