To
Select Correct Guard
Measure distance from under anti-cavitation
plate to the bottom of the skeg. See "A" on
drawing.
-
Example: If this distance measures 12", the Guard
diameter should be 12".
Select: Model 91112-4 Line Guard
The propeller diameter is always less than the distance from
under the anti-cavitation plate to the bottom of the skeg, usually
at least 1" to allow for 1/2" clearance below the anti-cavitation
plate and 1/2" above the bottom of the skeg. To select
guard size by propeller diameter only is not recommended. The
above mentioned example is the correct selection guide.
