Shaft-Transmission Alignment
Alignment between the engine transmission
output shaft and the propeller is critical. The
alignment was done at the factory and was
rechecked by the dealer after your yacht had
been in the water for 48 hours.
•
Have a marine mechanic inspect the align-
ment after the first 30 hours of operation.
From then on, have the alignment
rechecked after every 60 hours of opera-
tion. At any time, if unusual noise or
vibration is noticed, have the alignment
inspected immediately.
•
Shaft-transmission alignment should be
done 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 launch-
ing before final alignment adjustments by
a marine mechanic are made.
Shaft Log Packless Sealing
System
Read the PSS Shaft Seal Installation Instruc-
tions for maintenance and inspection details.
SYSTEM DAMAGE HAZARD!
•
If you suspect a shaft-transmission alignment problem, have a trained mechanic inspect the
alignment as soon as possible.
•
Continued use may lead to premature engine, transmission, shaft, shaft seal and/or
hull damage!
