Watercraft units such as jet skis provide immense enjoyment to their owners and renters. However, it would it’s important for jet ski owners to understand proper maintenance guidelines. Neglecting the maintenance of delicate jet ski parts can cause them to wear out and result in significant problems for the owner, leading to costly repairs at jet ski repair shops.
To ensure a long lifespan for the water vehicle, owners must undertake preventive maintenance such as a winterize procedure. Many owners may resort to DIY blogs and videos to repair their jet ski parts, assuming that watercraft repairs are similar to automobile repairs.
However, jet ski repairs can have complexities that even experienced handyman may not anticipate, as the smaller jet ski engine size can be deceptive when compared to an automobile engine. The following are five potential solutions for jet ski repairs that owners may need to address in the lifetime of their watercraft.
Replacing Jet Ski Parts
- Replacing the Fuel Lines:
During the initial diagnosis of engine failure, certain jet ski parts may be overlooked. Deteriorated fuel lines, in particular, can leave behind debris that can clog up the carburetor, resulting in slow and inefficient engine performance. Replacing fuel lines requires some research, as different jet ski models require different fuel line sizes - there is no one-size-fits-all solution for watercraft. To improve throttle response, fuel line return restrictors can be installed between the carburetor and the fuel tank. Additionally, using a fuel stabilizer can help maintain the fuel system's peak performance, preventing costly repairs in the future.
- Replacing the Jet Pump:
The device located at the bottom of lake jets is known as the jet pump, which contains an impeller that accelerates water pressure before it discharges through the rear nozzle of the jet ski unit. This results in increased engine control and performance. Signs of a worn jet pump include vibrations during idle mode. Some owners rebuild the jet pump every 4 to 5 years as part of their repair and maintenance procedures. The pump system also includes wear rings, which encase the impeller. Debris that chips away at these vital parts of the jet pump can negatively affect engine performance. Proper maintenance of the jet pump system is recommended by both jet ski owners and sales shops as part of a winterize procedure during the off-season.
- Replacing the Crankshaft:
Rusted crankshafts can cause engine problems in jet skis. Those who are rebuilding jet skis tend to prefer welded crankshafts, as the welds help hold the pins in place. These pins are crucial in holding the flywheel in place, which is the counterweight of the crankshaft. Some owners think that welding the crankshafts to the cylinders can prevent twisting of the unit. There are varying opinions among owners and jet ski repair shop merchants regarding the superiority of welded crankshafts.
- Changing the Battery:
Many vehicle owners tend to overlook the battery as a potential source of problems. Similarly, jet ski engine diagnosis often faces the same issue of neglecting the battery as a potential culprit. If left out in the cold for an extended period, a battery can lose its charge over time. It is often recommended to remove the battery as a way of winterizing the watercraft. Batteries should be stored in an environment that protects them from harsh cold and winds, such as a garage. "Smart" chargers can help maintain proper usage levels during the offseason. For extra protection, covering the battery terminals with rubber or cardboard can prevent arcing and help the unit maintain consistency over months of non-use. A battery charger can ensure that the unit is ready to go when it's time to pull the vehicle out of the garage for summertime rides on the water.
- Proper Sealing:
Seals are crucial components for the optimal performance of jet ski engines. Unfortunately, many jet ski owners are unaware of this fact and are not informed by sales associates during their purchase. Worn-out seals can cause oil to leak into undesired areas, leading to engine damage. Gaskets are the most commonly used seals for jet skis and are essential for filling gaps between mismatched engine parts. Proper gasket materials such as treated paper or metal are recommended, with metal being more expensive but better equipped to withstand external pressure. Checking for proper seals is a crucial part of the winterization process for jet ski vehicles. Gaskets are required for various jet ski parts, including crankshaft ends, exhausts, flywheel covers, and oil pumps. In summary, proper seals are imperative for the optimal performance and lifespan of a jet ski engine.
Buying a Jet Ski for the first time?
When someone new to jet skis searches for sales shops online, it's important to also consider the care and maintenance required for these watercrafts. Maintenance is often neglected until issues arise, but proper care can extend the lifespan and performance of the jet ski. When considering purchasing a used jet ski, it's crucial to thoroughly examine its parts and educate oneself about proper care for the specific model. The sales representative should be knowledgeable about technical repairs or have access to someone who can provide repair guidance. A crucial tip for saltwater users is to clean the jet ski thoroughly after each use, as saltwater is highly corrosive and can damage the motor. While not an exhaustive list, the five common jet ski repair solutions discussed and the recommended winterizing procedures can help prolong the life of the watercraft, allowing for more time on the water and less time and money spent on repairs.
