Shaft-Transmission Alignment
!
CAUTION
SYSTEM DAMAGE HAZARD!
•
If you suspect a shaft-transmission misalignment, have a qualified mechanic perform an
alignment inspection as soon as possible.
•
Continued use may lead to premature engine, transmission, shaft, shaft seal and/or
hull damage!
•
•
Alignment between the engine trans-
mission output shaft and the propeller
is very critical.
The alignment was performed at the
factory and was rechecked by the
dealer after the yacht had been in the
water for 48 hours.
TRANSMISSION-TO-PROP SHAFT COMPONENTS (TYPICAL)
•
An alignment inspection should be
performed by a marine mechanic as
part of the routine maintenance pro-
gram after the initial 30 hours of
operation, then every 60 hours and
whenever unusual noise or vibration
is noticed.
•
•
Shaft-transmission alignment should
be performed by a marine mechanic
since it requires moving the engine
and prop shaft.
To insure proper alignment after a
haul out or dry storage, wait 48 hours
after launching before final alignment
adjustments by a marine mechanic
are made.
