Yamalube 10W-40 Motor Oil for WaveRunners & Yamaha Jet Boats FAQs

Can I use automotive engine oil in my Yamaha WaveRunner or Yamaha Boat? 

While many boat owners wonder about this, the short answer is that WaveRunner or Yamaha Boat engines are jet propulsion engines and are vastly different from your automotive engine, so you’ll want to avoid using regular automotive engine oils. Use Yamalube 10W-40 4-stroke motor oil, which is specifically formulated for the rigors of the marine environment.

How is Yamalube 10W-40 marine motor oil different?

Yamaha has spent countless hours and resources to ensure that only the best Yamalube 10W-40 marine motor oil, specifically suited for the marine environment, goes into your WaveRunner or Yamaha Boat engine. PartsVu.com can confirm that this oil was formulated to withstand the harshest marine environments and most strenuous Yamaha WaveRunner or Yamaha Boat operations. Whether it’s extended full-throttle operation, engine-punishing “out of the hole” acceleration, or hours of trolling, genuine Yamalube engine marine motor oils can handle the job at hand.

Additionally, Yamalube oil delivers superior lubrication and anti-rust protection for engines in marine environments and works to guard against ring stick, carbon buildup, and varnish. Yamalube 4-stroke engine oils have the best anti-foaming formula available, and unlike passenger car oils, they are certified by the National Marine Manufacturers Association.

Aren’t all PWC or jet boat oil filters the same?

While most marine oil filters look the same, what’s on the inside counts most. Yamaha WaveRunner and Yamaha Boat oil filters are manufactured specifically to protect Yamaha marine engines, using only the finest components and construction methods available. This includes special filter media and metal filter media bases (instead of cardboard), to help them achieve a level of durability and filtration far superior to most aftermarket oil filters. From the quality of the materials used to their high-quality construction, Yamaha marine oil filters simply outperform and out-protect aftermarket alternatives.

How is a Yamaha jet propulsion engine different from a Yamaha outboard engine?

Yamaha’s jet propulsion system draws water into an enclosed impeller, accelerates it through a pump, and expels it through a nozzle to create thrust. In contrast, a traditional propeller system relies on an exposed propeller that pushes water backward. This design not only eliminates the external propeller but also enhances safety and allows for operation in shallow water.

Do I need to flush my WaveRunner's or Yamaha Boat's engine after every ride?

Yes, most definitely. Saltwater, sand, and debris can accumulate in the cooling system, causing clogs and corrosion. To avoid this problem, flush your WaveRunner’s or Yamaha Boat's engine after every ride, especially after saltwater use.

How to flush the engine:

1. Connect a garden hose to the flush port (see your owner’s manual for the exact location).
2. Start the engine before turning on the water.
3. Allow the engine to run for 2-3 minutes during the flush to eliminate contaminants.
4. Turn off the water prior to shutting down the engine.

Warning: Do not turn on the water before starting the engine, as doing so may force water into the engine, leading to hydrolock and significant damage.

**Pro Tip** If you ride your WaveRunner or use your Yamaha Boat on saltwater bodies, a high-quality salt remover, like Salt Off, is required to complement freshwater during the flushing process.

Can debris get sucked into the jet intake?

Debris, such as seaweed or small objects, may clog the intake, reducing performance. Yamaha jet boats come equipped with clean-out ports that allow operators to clear blockages without entering the water. Regular maintenance and inspecting the intake when operating in areas with heavy vegetation can help prevent this issue.
