Predelivery Preparation

Before starting Predelivery, read "General Information" and "Installation Require-
ments" completely.

Battery Connection

IMPORTANT: Engine electrical system is negative (–) ground.
1. Connect engine positive (+) battery cable (usually red) to positive (+) battery terminal.
2. Connect engine negative (–) battery cable (usually black) to negative (–) battery termi-
nal.
3. Make sure that all battery terminal connections are tight and then coat connections and
terminals with a battery terminal anti-corrosion spray to help retard corrosion.

Test Running Engine

If engine is to be tested on land, propeller must be removed.
IMPORTANT: If engine is to be tested on land, water must be supplied to seawater
pickup pump. DO NOT run engine above 1500 rpm.

Boat-In-The-Water Tests

IMPORTANT: Engine alignment MUST BE CHECKED with boat in the water, fuel tanks
filled and with a normal load onboard.
Avoid engine damage. Ensure that cooling water is supplied to the engine if it will
be run with boat out of the water. See instructions in the Operation, Maintenance
and Warranty Manual entitled "Flushing Cooling System," for instructions on con-
necting flush device.
ENGINE IDLE SPEED ADJUSTMENT (CARBURETED MODELS)
The engine should idle at rpm (as specified in "Operation, Maintenance and Warranty
Manual") with engine at normal operating temperature. If idle speed is incorrect, proceed
as follows:
IMPORTANT: In order to properly set idle speed, the ignition module MUST BE locked
in the "Base Timing Mode." This is necessary because of the "Idle Speed Control"
feature that exists in the ignition module. This must be done before the key switch
is turned to the ON or START position.
1. Connect a shop tachometer to engine.
2. Using a jumper wire, connect the ignition system "Timing Lead" (PUR/WHT wire) to a
good engine ground (–). This locks the ignition module into the "Base Timing Mode."
Refer to "Engine Wiring Harness" diagram in this manual.
3. Start engine and place the remote control lever in NEUTRAL, idle position.
4. Adjust idle speed to 650 rpm.
5. Stop engine. Readjust cable barrel and reinstall the throttle cable.
