About Service

A fantastic benefit to summer is breaking out your Jet Ski, WaveRunner, or SeaDoo and enjoying an entire season of lake fun. From visiting your favorite cove on the water to passing on the love of lake life to the next generation, there’s a lot to relish about owning a personal watercraft (PWC).
As much fun as PWC’s can be, properly maintaining them can be tedious and time-consuming. It is imperative to hire a professional and knowledgeable mechanic to service your watercraft. PWC’s need a lot of care and maintenance to continue performing to their best abilities. Mechanically neglected PWC’s can drastically decline performance and potentially shorten the lifespan of the watercraft. At Skiwi Marine, we alleviate the majority of responsibility by providing quality service and simple maintenance education to maximize your riding time on the water. Our 20 plus years of watercraft expertise delivers top-notch results to ensure your PWC stays fast and functional all season long.

PWC Test Tank

Skiwi Marine is the only location in the Las Vegas metro area equipped with a PWC Test Tank. The Test Tank is a total solution for your watercraft testing needs as it enables our staff to quickly and efficiently address mechanical, electrical, and water intrusion issues. The bunk design of our Test Tank securely holds the PWC, keeping it from jumping and bucking even at high RPM. A PWC tank test incorporated with a longevity evaluation is an essential step in the diagnostics process to assess any performance concerns.

What happens if you don't winterize your jet ski or boat?

If you don’t winterize your jet ski or boat, here are the potential risks: Water freezes and expands and can crack your engine block. Water may seep into unprotected spaces and rust engine components. Additionally, acidic and corrosive wastes are likely to cause buildup and potentially cause severe erosion destroying delicate parts in engines.

4-Stroke Engine Rebuild

Jet ski repair shops may charge hefty prices for ongoing Engine failures due to ignorance and/or neglect of engine care by jet ski owners is a common occurrence. Proper repairs, along with preventive maintenance, such as a winterization, are a must for watercraft engines as repairs can be expensive.
Skiwi Marine offers a variety of options for engine rebuilds or motor replacement. With all engine failures, it’s important to find the root cause of the original failure and address the issue before a rebuild or replacement. After a rebuild or motor replacement your watercraft is tank tested to ensure adequate cooling is occurring, any water leaks can be addressed and the engine given some load to insure it’s running correctly.

What We Offer

Battery charge or replacement

The battery is often overlooked as a potential source of problems. When diagnosing watercraft problems it’s important to have a good power source and we always start there. You would be amazed at the number of watercraft problems that are solved simply by replacing the battery. Just for the record, a new battery is not one you “bought last summer”.

What We Offer

Hull Intrusions

Running jet ski’s up on the rocky beaches will cause damage to the gelcoat & fiberglass of your hull. This may eventually cause massive hull delamination. When your watercraft comes in for service we inspect the hull for any damage. We may even Skiwi has its own fiberglass & gelcoat division where we can promptly repair any hull issues. Skiwi Marine is also a preferred repair shop for many insurance companies.

What We Offer

Drain and replace fuel with a complete system check

Gas does not store well and will start to go bad after around 6 weeks. Fuel will break down and separate otherwise. This will cause significant damage to your fuel system. We regularly have to replace fuel pumps that range in price from $650-$1000 and clean tanks that have a black tar lining the inside. It’s time consuming to clean and both conditions could have been easily prevented. If your watercraft will not be being used for some time we recommend filling the tank and adding a 16oz can of Seafoam into the fuel tank.
