5 Locations To Serve You!
Whether you’re cruising the coastline, carving waves, or spending a weekend on the lake, maintaining your watercraft engine is key to reliable performance and long-term enjoyment. From personal watercraft (PWC) like Jet Skis and Sea-Doos to full-size boats, a well-maintained engine ensures your ride runs smoothly, efficiently, and safely. At Del Amo Motorsports, we’re more than just a premier powersports dealership in Southern California—we’re your trusted partner in keeping your watercraft in top shape year-round.
Watercraft engines operate in some of the harshest environments: high-revving performance on water, salt exposure, fluctuating temperatures, and moisture-rich conditions. Without regular maintenance, these factors can cause corrosion, performance issues, or even catastrophic engine failure. Preventative care not only protects your investment but also guarantees a safer and more enjoyable experience every time you hit the water.
Regular engine maintenance will:
Extend the life of your PWC, Jet Ski, or boat
Improve fuel efficiency and power delivery
Reduce the risk of breakdowns or costly repairs
Ensure compliance with warranty and manufacturer service guidelines
At Del Amo Motorsports, our factory-trained technicians and certified watercraft service team recommend a routine maintenance schedule tailored to your usage, model, and environment. Whether you own a Yamaha WaveRunner, Sea-Doo, Kawasaki Jet Ski, or a sport boat, here are the most essential maintenance tasks to keep in mind:
Saltwater and debris can wreak havoc on your watercraft’s cooling and exhaust systems. Flushing your engine with fresh water after each ride prevents buildup of salt, sand, and silt that can lead to corrosion or overheating. A simple flush using a hose and engine flush kit can make a world of difference.
Just like a car or motorcycle, your watercraft’s engine oil needs to be changed regularly. Old oil can become contaminated with moisture and particles, affecting engine performance. Changing the oil and oil filter at least once a season (or every 25-50 hours of use) keeps the engine running clean and cool.
Spark plugs are vital for proper combustion and smooth starts. Over time, they can wear out or become fouled by moisture and oil. Routine inspection and timely replacement ensure optimal ignition and throttle response.
Blockages, leaks, or cracked hoses can lead to overheating. During seasonal maintenance, the cooling system should be inspected for debris, corrosion, and proper function to keep your engine temperature regulated.
Fuel stabilizer is a must if you’re storing your PWC or boat for extended periods. Without it, the fuel can break down and clog injectors or carburetors. Also, replace your fuel filters regularly and inspect for signs of leaks or deterioration.
Always charge and inspect your marine battery between uses. Corroded terminals or a weak battery can leave you stranded on the water. Use a trickle charger when the watercraft is stored to maintain battery health.
