⏱ When to Service a Vetus Engine

Regular service intervals are crucial. Most Vetus engines require a full service every 100 running hours or at least once a season. Immediate service may be required if you notice:

• Unusual noises or vibrations
• Hard starting or loss of power
• Smoke from the exhaust
• Leaking fluids (oil, fuel, coolant)

🛠 Vetus Engine Service Checklist

• Change engine oil & filter – Warm up engine, drain oil, replace filter, refill with marine-grade oil.
• Replace fuel filters – Swap both primary and secondary filters, bleed air from fuel system.
• Inspect cooling system – Replace raw water impeller, check coolant levels, inspect hoses & clamps.
• Check belts – Inspect alternator & pump belts for cracks or glazing, replace if worn.
• Electrical checks – Test battery, inspect wiring for corrosion, confirm smooth throttle/gear operation.
• Final test run – Start engine, check for leaks, confirm oil pressure & water flow.

📦 Vetus Service Parts & Kits

Using the right parts ensures reliable servicing. Genuine Vetus service parts include:

For convenience, you can also buy complete service kits. These bundles include filters, impellers, gaskets, and seals in one package—making maintenance easier and reducing the chance of missing a part.

💧 Oils, Liquids & Additives

Marine engines demand the correct fluids. Vetus-approved oils and additives are specially formulated to protect in harsh conditions:

• Engine oil – Correct SAE grade, marine-rated.
• Gear oil – For transmissions and gearboxes.
• Coolant – Protects against corrosion and overheating.
• Fuel additives – Stabilizers, biocides, injector cleaners.
• Marine grease – For linkages, seals, and moving parts.

🔄 When to Replace Instead of Repair

Sometimes servicing is not enough, and replacing the engine is the smarter choice. Consider a new Vetus engine if:

• The engine has severe internal damage (cracked block, failed crankshaft).
• Repairs are frequent and costly.
• Spare parts are no longer available.
• Corrosion has compromised structural integrity.
• You want improved performance or fuel efficiency.
