MODELS WITH CLAMP SCREWS:
Some outboards come with transom bracket clamp screws. The
use of clamp bracket screws alone, is insufficient to properly and
safely secure the outboard to the transom. Proper installation of
the outboard includes bolting the engine to the boat through the
transom. Refer to Installation ‑ Installing Outboard for more
complete installation information.
Failure to correctly fasten the outboard could result in the
outboard propelling off the boat transom resulting in property
damage, serious injury, or death. Before operation, the
outboard must be correctly installed with the required mounting
hardware.
If an obstacle is struck at planing speed and the outboard is not
securely fastened to the transom, it is possible the outboard
could lift off the transom and land in the boat.

Exhaust Emissions

BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a deadly gas that is present in the
exhaust fumes of all internal combustion engines, including the
engines that propel boats, and the generators that power boat
accessories. By itself, CO is odorless, colorless, and tasteless,
but if you can smell or taste engine exhaust, you are inhaling
CO.
Early symptoms of carbon monoxide poisoning, which are similar
to the symptoms of seasickness and intoxication, include
headache, dizziness, drowsiness, and nausea.
