OUTBOARD INSTALLATION
TRANSOM MEASURING AND DRILLING
Transom Height
Make sure the transom height matches the length
of the outboard to be installed.
A 19 to 21 in. (48.3 to 53 .3 mm) transom height
•
uses a 20 in. (50.8 mm) shaft outboard.
The shaft length of the ou tboard being installed
•
should come close
height of the boat.
Refer to SPECIFICATIONS in out board Opera-
•
tor's Guide for transom height.
Determine transom height by measu ring from the
top edge of the transom, along the centerline.
For d ual-outboard inst allations, tr ansom height
should be measured at the outboard centerlines.
Use a straightedg e as a reference to extend the
bottom of the boat.
Position the str aightedge along ce nterline. The
distance from the top ed ge of the straightedge to
the top edge of the transom is the actual transom
height.

All models use the st andard ABYC 4-Bolt mount-
ing pattern.
Use T ransom drill fixture
P/N 385368, as a gu ide for co rrect h ole p lace-
ment. If drill fixture is unavailable, refer to Drilling
and Hardware Diagrams on p. 36 for measu re-
ments.
Position drill fixture on top of transom or bracket
and align indicator points with centerline.
Transom drill fixture P/N 434367 (heavy duty)
The indicators are af fected by the square ness of
the top edge of the transom. If either side of the
fixture must be raised mo re than ¼ in. (6 mm)
above the transo m's top sur face to make
indicators align, the transom must be modified.
IMPORTANT:
edge of the transo m is stra ight. Po sition the drill
fixture b ased on me asurements aligning it to th e
bottom of the hull.
NOTICE
Maintain at least 1.75 in. (45 mm) of
transom surface above the top mounting
m of
bolts.
