Maintenance
58
Check the splines / shear pin for wear or
damage.
Check for fish line tangled around the pro-
peller shaft.
Check the propeller shaft oil seal for dam-
age.
NOTE:
If the shear pin equipped: it is designed to
break if the propeller hits a hard underwater
obstacle to help protect the propeller and
drive mechanism. The propeller will then spin
freely on the shaft. If this happens, the shear
pin must be replaced.

On counter rotation models, be sure to
use a propeller intended for counterclock-
wise rotation. These propellers are identi-
fied with the letter L after the size
indication on the propeller. Otherwise the
boat could move in the opposite direction
from that expected.
