• For boats with a dual cooling system - cleaning the cooling system - as needed
• For boats with a dual cooling system - check the condition of the coolant - at least once a year
• Coolant change - every five years
• Anodes - check every 30 days. If the boat is operated in salt or mineralized water, more frequent inspections are required.
• External engine treatment with anti-corrosion agents - for fresh water, every 60 days; for salt water every 30 days
• For offshore boats - flushing the cooling system - after each use

• Above 10 degrees Celsius - SAE 15W40 Oil
• Below 10 degrees Celsius (well, what if?) - SAE 5W30 oil
• Except XS550 / XR550 engines
• For engines XS550 / XR550 Mobil 1 Synthetic 5W30 oil is used
• For PCM Transmission - Dextron III
• For PCM V-Drive Gearbox Oil R190250
• For Walters V-Drive gearbox SAE 30 oil
• For all Hurth - Dextron III transmissions

• The minimum oil volume in the engine with a new filter is about 3.7 liters
• Transmission PCM 1: 1 - 1.9 liters - Dextron III
• Transmission PCM 1.23: 1 - 1.9 liters - Dextron III
