WARNING
Outboard must be fastened to boat transom one
of two ways: 1. permanently fastened to transom
with thumb screws, and mounting bolts (pro-
vided), or 2. secured to the transom using the op-
tional outboard mounting kit (P/N 812432A4).
Should the outboard strike an underwater object
or be steered into a sharp turn, failure to fasten
outboard correctly to the boat transom with
mounting bolts or optional mounting kit could re-
sult in outboard ejecting suddenly off boat tran-
som causing serious injury, death, boat damage,
or loss of outboard.
1. Center outboard on the transom.
2. Position outboard so the anti-ventilation plate is
within 1 in. (25.4 mm) of the boat bottom.
