Buying and owning a boat is a big commitment — and an expensive one. However, neglecting the maintenance your boat needs will end up costing you a lot more than if you perform regular maintenance and upkeep on it. Our professionals know that keeping your boat in pristine condition comes from proper maintenance like getting a regular oil change. If your boat requires servicing, visit our experts at Marine Diesel Specialists for the best service.

Actively changing the oil in your engine, along with the filter, can keep the engine working well and keep repair costs low. Other important factors to remember about a regular oil change are:

  • Routine oil changes keep your engine properly lubricated and clean.
  • On-time oil changes will clear out any debris in the engine before it causes damage.
  • An oil change will keep your engine parts cool and lubricated.
  • Regular oil changes will keep your engine running longer.
  • An oil change is key for better engine performance.
  • Oil changes are designed to protect your engine.

How Much Is an Oil Change?

Some oil changes for a single-engine can cost hundreds of dollars and many hours of labor if you don’t do them on time or if you don’t seek the help of a professional repair shop.

How Often Should You Change the Oil in a Boat Engine?

If you are wondering just how often you need to perform an oil change on your boat’s engine, the answer is typically every 100 hours and at least once a year – whichever comes first. We recommend that even if your engine is capable of going for longer periods of time between an oil change, you make sure to do it during these times anyway. This will ensure that the life of the engine is carried out to full term.

When to Have an Oil Change on an Older Engine

If your boat engine is a little older, you will want to make sure to really keep up with maintenance to make sure it performs at its optimal level. This means after every 100 hours, you will want to have an oil change, or at least once a year. The more frequently you change the oil, the better the chances your older boat engine will last longer.

When to Have an Oil Change on a Newer Engine

For newer engines, oil changes are not as frequent but should still be done regularly to keep your engine healthy. During the break-in phase of your boat’s engine, we recommend getting an oil change after the first 20 hours; then you can extend the oil change time to 100 hours or once a year.
