masking tape directly onto boat where mounting
holes will be drilled to help prevent fiberglass from
chipping.
Measure the transom height of your boat. The boat
bottom should be aligned or be within 1 in. (25mm)

ing holes in the transom brackets that will place the
outboard nearest to the recommended mounting
height.

stallation is water-tight.
