Before hitting the water, jet ski enthusiasts should perform a thorough pre-ride inspection to ensure optimal performance and safety. This checklist covers essential areas that require attention before every ride.
Fuel System Check
A jet ski's fuel system is crucial for its performance. Riders should begin by removing the seat and checking the engine compartment for gas vapors [1]. This step is vital because jet skis lack active ventilation systems, which can lead to the accumulation of potentially dangerous fumes. It's important to vent the engine compartment for a few minutes before starting the engine to eliminate any vapors.
Next, inspect the fuel tank for damage and ensure the fuel lines and connections are secure. Using fresh fuel with a stabilizer can help maintain the jet ski's performance [2]. Proper fuel levels are essential for a smooth ride, so always check and top up if necessary.
Battery and Electrical System Inspection
A healthy battery is crucial for a trouble-free jet ski experience. Before each ride, check the battery's charge level. A fully charged jet ski battery should register between 12.6 to 12.7 volts when tested after sitting for at least an hour [3]. If the reading is 12.4 volts or lower, the battery may need charging.
Inspect the battery for signs of corrosion, especially on the cables, and clean if necessary [4]. Corrosion can lead to hard starts or a dead battery. Also, examine the entire electrical system for any potential spark hazards, as this could be dangerous when combined with gas fumes [4].
Hull and Component Assessment
A visual inspection of the hull is essential to identify any damage that could affect the jet ski's performance. Look for cracks, chips, or scratches on the hull [2]. Pay special attention to the drain plugs, ensuring they are securely installed, as missing drain plugs are a leading cause of sinking jet skis [1].
Check the steering and throttle systems to confirm they're working correctly. Inspect the seat and storage compartment lids to ensure they're properly secured. Remove any water from the bilge if present [1]. Lastly, it's advisable to start the jet ski briefly (about 15 seconds) on the trailer before launching to verify it starts properly [1].
POST-RIDE MAINTENANCE ESSENTIALS
Cleaning and Flushing
After every ride, jet ski owners should thoroughly clean their watercraft. This step is crucial, especially after use in salt water, as salt can quickly corrode important parts [5]. Begin by removing all gear from storage areas and washing the hull to eliminate algae and dirt. Spray off any salt residue with fresh water and wipe down all surfaces with a microfiber cloth [6].
Next, flush the exhaust system with water to remove sand or debris. Run the engine at idle for 2 minutes, stop the water, then turn off the engine. Create a solution of equal parts water and RV antifreeze, then flush the antifreeze outlet with water. Use a bilge or water pump to send the 50/50 solution into the exhaust and repeat the flushing process [6].
Engine Compartment Inspection
After cleaning, inspect the engine compartment for any signs of damage or wear [7]. Check the oil level and quality, ensuring it's within the manufacturer's specifications. If the oil appears milky, contact a service agent immediately, as this indicates water contamination [8]. For Sea-Doo models with closed-loop cooling, check the coolant level as well.
Examine the fuel system, including hoses and connections, for any signs of wear or damage. As jet skis age and fuel changes, it's important to replace all fuel hoses periodically [9]. Inspect the battery cables and ground connections for any loose bolts or corrosion [9].
Proper Storage Practices
For long-term storage, add a fuel stabilizer to the fuel tank to prevent debris buildup and fuel degradation [5]. Remove the battery and store it in a cool, dry place, using a trickle charger to maintain its condition [5]. Ensure all water is drained from the jet ski by checking the drainage points specified in the owner's manual [5].
Lubricate necessary parts to prevent corrosion and maintain optimal condition [5]. For winterization, change the oil and filter to prevent thickening that can cause engine problems in the next season [6]. By following these post-ride maintenance practices, jet ski owners can ensure their watercraft remains in top condition for future adventures.
ROUTINE MAINTENANCE TASKS
Oil and Filter Changes
Regular oil changes are crucial for jet ski maintenance. Most manufacturers recommend changing the oil annually or after every 50 engine hours, whichever comes first [10]. This is because oil can become contaminated with moisture and carbon during operation, reducing its effectiveness. For 4-stroke jet skis, it's essential to use specially formulated marine engine oil, typically 10W-30 2-stroke marine engine oil, which provides exceptional protection and withstands high temperatures [10].
To perform an oil change, owners should gather the necessary materials, including recommended oil, a new filter, a suction pump, rags, an oil container, and a filter wrench [11]. The process involves warming up the engine, extracting the old oil using a suction pump, replacing the filter, and refilling with the appropriate oil [11].
Spark Plug Replacement
Replacing spark plugs is a simple yet effective maintenance task. It's recommended to change spark plugs annually [10]. This small investment, usually costing only $2-3, can significantly improve performance. Owners can replace spark plugs themselves if they have the necessary tools, or have a mechanic do it quickly [10].
Lubrication of Components
Proper lubrication is essential for protecting jet ski components from corrosion and maintaining optimal condition. After the riding season, it's crucial to drain and replace all fluids from the engine, including fuel and motor oil [10]. This helps reduce residue formation and protects the engine from corrosion, ultimately increasing its lifespan [10].
SEASONAL JET SKI CARE
Winterizing Your Jet Ski
As the days grow colder, jet ski owners must prepare their watercraft for winter storage. This process, known as winterization, is crucial for maintaining the jet ski's condition during the off-season [12]. To begin, owners should clean out storage compartments, wiping them down thoroughly and leaving them slightly open to prevent moisture accumulation [12].
Next, it's essential to remove water from the exhaust system. Owners should tilt the jet ski up at the front and run the engine in short bursts until no more water comes out [12]. In areas with freezing temperatures, running a 1:1 mixture of water and RV antifreeze through the system is recommended to prevent damage from expanding ice [12].
De-Winterizing for Summer
When spring arrives, de-winterization prepares the jet ski for the upcoming season. This process involves several key steps. First, owners should charge the battery using a smart charger the night before [13]. Next, they should flush the jet ski by attaching a garden hose to the flushing port and running the engine for two minutes to check for leaks [13].
