Buying a jet ski is a significant investment, and your planned budget may be blown out long-term without the right attitude toward preventative care.

Jet ski maintenance is an ongoing responsibility, with regular and semi-regular checks of certain components necessary to keep your craft in optimal condition.

Did you know maritime law states a vessel must be maintained as seaworthy at all times?
To keep your vessel seaworthy all the time, you have to keep it well serviced. Doing this is one of the best ways to prolong the life of your jet ski. Regular oil changes (to minimise engine wear), regular greasing around bearings (to prevent expensive repairs), and checking the many bolts, clamps, sensors and ECU are all safety “must do’s”.
We’ve listed five important considerations you must make to keep your jet ski running smoothly.


It’s especially important for first-time jet ski owners to refer to their manual as often as possible. Modern manuals carry details on every component of your PWC, allowing you to better understand how everything works. Never attempt any DIY repairs on your jet ski without knowing exactly what you’re doing, as you can cause more harm than good.


Regardless of whether you ride in fresh or salt water, your PWC should be flushed after every single ride. Flushing removes salt, sand, algae, weeds, and shells etc, from the engine and prevents damage and corrosion.

Modern jet skis are fitted with a hose connector for interior cleaning. Simply attach a hose to the connector (hose MUST be turned off) before starting your engine. Once the engine is running, turn the hose on and keep it on for approximately two minutes. Allow your PWC to keep running for a few seconds after turning the hose off, and give the throttle a few bursts to drain water from the exhaust. Remember to keep your engine running at all times when adding water to the interior.


Modern jet skis are designed to last, but saltwater is corrosive to fiberglass and can lead to problems down the line. First rinse your jet ski, before using warm soapy water and a sponge to thoroughly remove all salt residue. Set your hose to a low pressure when rinsing the soap off.


Jet skis are resilient and built to absorb minor damage, but will show signs of mechanical wear over time in the same way that cars do. Cracks or fissures in the fiberglass of your jet ski need to be checked by a professional as soon as possible, as hull damage can expose interior components to significant damage.

It pays to check the components of your jet ski after prolonged use. Once you know where everything is, you’ll be able to confidently check hoses, clamps, wiring, throttle cables and other components to ensure everything is in good working order.


Certain checks and replacements should only be made by fully qualified technicians. They’ll be able to take care of the time-consuming jobs that are required semi-regularly.

You can expect technicians to change your engine oil and filter, lubricate bearing fittings and seals, replace pump oil and generally ensure everything is as it should be.
