Owner’s Manual Maintenance Requirements

Cleaning
• Use a small piece of Emory cloth to clean the dark carbon coating off the plug by rubbing it against
the center electrode and the side electrode.
• Brake cleaner may be use to remove grease and excess oil.
• If necessary, use a wire brush to remove buildup trapped within the threads.
• Wipe the plug down thoroughly with a rag after cleaning to remove all of the residue.
Gap Check
•
The optimal gap for the spark plug is (.035 in)
•
Insert a gap tool into the space between the spark
plug’s body and the electrode that sticks out of it.
Use the tool to measure the gap, then either pry
the electrode further from the body to increase
the gap or press it closer to the body to decrease
it until the gap matches.
•
Gap Tool is included with the Raider Outboards
Maintenance Tool Kit.
Install
• Install spark plug, fully hand-tighten, and then use
16mm deep well socket to tighten to torque (20 lb
ft).
• If a torque-wrench is not available when you are
fitting a spark plug, a good estimate of the correct
torque is 1/4 to 1/2 a turn past finger-tight. Have
the spark plug adjusted to the correct torque as
soon as possible with a torque-wrench to specified
torque.
