Refer to Engine Monitoring and review your en-
gine’s warning system self-test routine. During your
preseason start-up, make sure the warning system
self-tests properly. If it does not, see your DEALER.
Follow Engine Starting and start the engine. Let it
idle while you:
Observe running quality – if poor, refer to Trouble
Check Chart or see your DEALER.
Observe water pump operation. Water must flow
from the water pump indicator in a steady stream. If
it does not, shut OFF the engine and investigate.
Refer to Engine Overheating.
WARNING
Keep the battery connections clean, tight
and insulated to prevent their shorting or
arcing and causing an explosion. If the bat-
tery mounting system does not cover the
connections, install covers. Check often to
see that connections stay clean and tight.
Stop the engine and check the fuel system for
leaks.
WARNING
Failure to check for fuel leakage could allow
a leak to go undetected, resulting in fire or
explosion.

Service
Installation
Before servicing the battery or the outboard, re-
move both battery cables from the battery, BLACK
(–) cable first. Keep metal objects from contacting
either battery post.
Read and understand the safety information sup-
plied with your battery BEFORE you begin installa-
tion.
IMPORTANT: Service electrical components only
while the outboard is NOT running. Be careful when
identifying positive and negative battery cables and
posts. If you touch the wrong post with a battery ca-
ble, even briefly, the charging system will be dam-
aged.
IMPORTANT: Place the battery in a hold-down
system and in a location that is easily accessible for
frequent checking and recharging.
Place a large-surface star washer over the battery’s
positive (+) post. Stack the RED battery cable from
the motor on the star washer, then install cables
from accessories (if any). Finish the connection
with a hex nut and tighten it firmly with a wrench.
WARNING
Connect the motor’s BLACK battery cable to the
battery’s negative (–) post in the same manner.
Battery electrolyte is acidic — handle with
care. If electrolyte contacts any part of the
body, immediately flush with water and seek
medical attention.
