Screw Models
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 (shown below).
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. Optional Outboard Mounting kits shown, must be
used if outboard will not be permanently fastened
to the transom with mounting bolts.
