🔌 Function

Heats the combustion chamber before and during cranking so the engine will fire and run cleanly from cold.

⚠️ Common Signs of Failure

• Hard starting from cold that improves once the engine is warm
• White smoke and a rough, lumpy idle for the first minute after a cold start
• Preheat warning lamp staying on or flagging a fault
• Plug tip found swollen, eroded or burnt back on removal
• Higher than normal current draw on the preheat circuit

🛠️ Service Notes

• The SOLAS marking is part of the specification — replace like for like on a vessel certified to that standard
• Confirm the system is 12 V before ordering, as a 24 V installation takes a different plug
• Test the plugs as a set, since one failed plug usually means the others are close behind
