Simple Maintenance Tips for the Yanmar 8LV370 Inboard Diesel Engine
Maintenance of your Yanmar engine is a matter of treating the engine as it should be treated, and this means better performance, economy, and lifespan. The following is a step-by-step guide to the most important maintenance procedures and intervals that you should adhere to:
1. Daily and Pre-Use Checks
Prior to starting your engine in the morning or prior to going out onto the water for the day, there are a few quick checks to be done. The checks will not take a minute but will save serious problems down the line.
Checklist:
- Engine oil check – Top up if below level. Use Yanmar-recommended lubricants only.
- Coolant check – Top up with correct coolant mix.
- Visual check – Check for leaks, rust, loose connections.
- Fuel quality and level – Free of water or no fuel contamination.
- Battery voltage – Clean terminals and fully charged battery.
Pro Tip: Small issues can be noted in a daily inspection logbook before they become costly problems.
2. Weekly Service Tasks
Every week or 10 hours of usage, take some more time to delve deeper into inspections.
Things to Do:
- Clean seawater strainer – Prevents rubbish from ruining your cooling system.
- Check belt tension – Loose belt will damage alternator and pump operation.
- Check engine mounts – Tighten and check for wear.
- Check exhaust system for clogging or leaks.
3. 50-Hour or Monthly Maintenance
Every 50 hours of operation or monthly, you need to do the following:
- Change engine oil and filter – Utilize genuine Yanmar filters for better performance.
- Clean and check turbocharger for carbon build-up.
- Check fuel lines for cracks or leaks.
- Lubricate linkages and moving parts.
- Inspect and clean air filters – Replace as needed.
4. 100-Hour Maintenance Intervals
Every change of season or every 100 hours of engine operation, whichever comes first, perform more extensive inspections:
- Replace water separators and fuel filters.
- Drain coolant and inspect; flush system if necessary.
- Inspect and test starter, alternator, and electrical system.
- Tighten hose clamps and inspect for wear or corrosion.
5. 250-Hour or Annual Service
Every 250 hours or one year, whichever comes first, conduct a complete service:
- Replace seawater pump impeller.
- Drain and change coolant.
- Injector servicing and fuel injection system calibration check.
- Drain, clean, or change heat exchanger core.
- Valve clearance check and adjustment.
- Change air cleaner element.
If you are not comfortable with these more involved procedures, have your Yanmar dealer service it. We will do it for you.
6. Every 500 Hours or Two Years
Now more extensive maintenance must be performed:
- Inspect and/or replace turbocharger as needed.
- Replace engine mounts if worn out.
- Service gearbox and oil change.
- Inspect exhaust elbow for rust and blockage.
7. Storage and Winterization
If you are wintering or long-term storing your boat, then perform the following very important steps:
- Drain cooling water and fill with anti-freeze solution.
- Fill tank and treat with fuel stabilizer to prevent breakdown.
- Fog with fogging oil through intake system to protect internal components.
- Disconnect and store the battery safely.
- Seal intake and exhaust openings to prevent moisture or animals from entering.
8. Use Genuine Yanmar Parts and Fluids
This is a no-brainer: always use genuine Yanmar parts and oils. Generic parts will be cheaper in the short term but can lead to serious performance issues or void your warranty.
