Stopping The Engine - MerCruiser 350 MAG Owner's Manual

Section 3 - On The Water
Without sufficient cooling water, the engine, the water pump, and other components will
overheat and suffer damage. Provide a sufficient supply of water to the water inlets during
operation.
Explosive fumes contained in the engine compartment can cause serious injury or death
from fire or explosion. Before starting the engine, operate the bilge blower or vent the
engine compartment for at least five minutes.
NOTE: MerCruiser DTS models are equipped with SmartStart. The SmartStart feature
incorporates push button starting. Rather than holding the start button or key switch to start
the engine and then releasing it when the engine starts, SmartStart completely controls
the starting process. When the start button is pushed, the DTS system signals the engine
PCM to start the engine. If the engine does not start, the starting process times out after a
few seconds or when the engine reaches 400 RPM. Attempting to start the engine with the
engine already running will turn the engine off.

drive into gear only when the engine is operating at idle.
