Stand-out advantages

• Two gallons of Yamalube 10W-40 mineral oil absorb heat and cushion internal parts during long summer pulls.
• Dual 5GH-13440-71-00 oil filters and twin 6B6-14451-00-00 air filters keep lubrication clean and airflow balanced across port and starboard engines.
• Eight NGK CR9EB plugs arrive pre-gapped, firing crisply for smoother idle.
• Matched impellers—68N-R1321-10-00 (starboard) and 6B5-R1321-00-00 (port)—restore strong coolant flow, crucial when idling through no-wake zones.
