Installing Outboard – Thumb Screw Models
WARNING
Outboard must be fastened to boat transom one of two ways: 1. permanently fas-
tened to transom with thumb screws, and mounting bolts (provided), or 2. secured
to the transom using the optional outboard mounting kit (shown below). Should the
outboard strike an underwater object or be steered into a sharp turn, failure to fas-
ten outboard correctly to the boat transom with mounting bolts or optional mount-
ing kit could result in outboard ejecting suddenly off boat transom causing serious
injury, death, boat damage, or loss of outboard.
IMPORTANT: Optional outboard mounting kits shown, must be used if outboard will
not be permanently fastened to the transom with mounting bolts.
