Good Ventilation

Ventilate the passenger area, open the side curtains or forward hatches to remove fumes.
1. Example of desired air flow through the boat.

Poor Ventilation

Under certain conditions, permanently enclosed or canvas enclosed cabins or cockpits with
insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide
detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers and passengers in an open
area of a stationary boat that contains or is near an operating engine may be exposed to
a hazardous level of carbon monoxide.

Basic Boat Operation

Launching and Boat Operation

IMPORTANT: Install bilge drain plug prior to launching boat.
To avoid possible ingestion of water that can damage engine components, do not turn
the ignition key off when the engine is above idle speed. When launching your boat from
a steep ramp, enter the water slowly. Do not use the lanyard stop switch to shut off the
engine above idle speed. When coming off plane, if a large following wave may roll over
the boat's transom, apply a short, light burst of throttle to minimize the wave action against
the stern of the boat. Do not come off plane quickly, shift into reverse and shut off engine.
