As the summer sun starts to heat up the waters around Chicago and beyond, jet ski enthusiasts everywhere are gearing up for unforgettable weekends on the lake. If you’re planning to get your Personal Watercraft (PWC) back on the water, now’s the perfect time to invest in key upgrades that will elevate your performance, boost safety, and turn heads at every shoreline. At EPM Motorsports, we specialize in helping riders enhance their machines with high-quality parts, expert service, and customized solutions. Whether you’re racing across local lakes or cruising with friends, here are the answers to the most common upgrade questions we hear—and how our services make it all happen.
Absolutely. A new exhaust is one of the fastest ways to increase horsepower and improve throttle response. An enhanced system reduces back pressure, allowing your engine to breathe easier and rev higher. You’ll notice the difference the first time you open up the throttle on open water.
Consider switching to an aftermarket free-flow or waterbox for an immediate boost. Quality options are available that work with most Sea-Doo, Yamaha, and Kawasaki models.
Not sure what is best for your PWC? Our premier jet ski and PWC repair in Chicago includes consultation and expert installation to ensure your modifications are optimized for your riding style.
Yes—when it’s done right. Your stock ECU (Engine Control Unit) is built for general use, not maximum power output. Reflashing your ECU allows you to unlock hidden power and increase top speed by modifying fuel maps, ignition timing, and rev limiters. The key is working with professionals who use proven data and understand your specific model.
Pair your ECU flash with an enhanced air intake and exhaust for a complete Stage 1 package that transforms how your PWC rides.
Through our engine rebuilds, we’ll safely remap your ECU using proven data, ensuring peak power without sacrificing reliability. You’ll notice the difference the first time you squeeze the throttle.
Your impeller is responsible for transferring engine power into forward thrust. Stock impellers are built for general use and reliability, but they leave capability on the table. Moving to a precision-machined stainless steel impeller will result in improved acceleration, top-end speed, and fuel efficiency—especially if you’re an aggressive rider or run in rough conditions.
High-quality options are made for aggressive riders and racers. Combine it with an enhanced pump for superior hook-up in rough water, and you’ll feel like you’re on a completely different machine.
Our service and repairs include installation, testing, and tuning to make sure your PWC is dialed in perfectly.
More than you’d think. Enhanced airflow means improved combustion—and more power. A quality air intake will help your engine run cooler and stronger, especially during long summer rides when heat buildup becomes an issue. Plus, your throttle response improves noticeably.
Go for a cold air intake built for your PWC model. These pull in cooler, denser air from outside the engine compartment for stronger output across the entire RPM range.
At EPM Motorsports, we include upgraded intakes as part of a balanced package, so everything works together for maximum results.
Speed isn’t everything—control is crucial, especially in choppy conditions or tight turns. Enhancing your sponsons, intake grate, and ride plate can dramatically improve stability and cornering. These modifications help you maintain control at high speeds, reduce sliding out in turns, and eliminate porpoising (that bouncing motion at speed).
Install adjustable sponsons to customize your handling, a top-loading intake grate to improve hook-up, and a longer ride plate to reduce porpoising. The difference in confidence and command is immediate.
If you’re not sure where to start, we can evaluate your setup and recommend the best modifications for your needs based on how and where you use your PWC.
Both. A new seat not only gives your machine a fresh look but also improves rider grip and long-term ease. Stock seats get slippery when wet and can cause fatigue on long sessions. Custom seat covers provide enhanced traction, reduce sliding around in aggressive maneuvers, and keep you relaxed all day.
Go with a gripper seat cover in a color scheme that matches your hull. Quality options combine function and style—you get the benefits and the head-turning aesthetics.
We can help you select and install a seat setup that feels as good as it looks.
If you’re serious about control and ease, yes. Moving to aftermarket handlebars and adjustable steering gives you more precision, an improved position, and a sportier feel. This modification is especially useful for stand-up and aggressive sit-down riders who need precise input during hard cornering or jumping wakes.
Consider a billet aluminum steering setup and handlebars with adjustable height and angle. Being able to dial in your position makes a huge difference during long sessions on the water.
If you’re going all-in this summer, let us install a fully integrated control setup for maximum ergonomics and command.
Absolutely, and it’s one of the most popular modifications we do. Today’s riders want speed and entertainment. Marine-grade Bluetooth speakers, GPS units, and LED lighting make every session more enjoyable and safer—especially if you’re out during dawn or dusk.
Install a waterproof Bluetooth audio setup with handlebar-mounted controls for easy operation. Add LED nav lights and underwater LEDs to turn heads during night rides and improve visibility.
We can integrate electronics and wiring cleanly for a factory-style finish that looks professional and holds up to water, vibration, and sun exposure.
Yes—a dirty or oxidized hull slows you down, literally. Surface drag from grime, oxidation, and scratches can cost you speed and fuel efficiency. And if your PWC’s hull is scratched or faded, it’s more prone to damage and water absorption over time.
Apply a ceramic coating to protect your paint and reduce drag. Add hull decals or wraps for a look that also provides an extra layer of protection.
Our detailing service includes full cleaning, polishing, and protection—perfect for making your PWC shine at the start of the season and keeping it protected all summer long.
Before launching into summer, make sure your PWC is in top shape. Old spark plugs, low fluids, or a dying battery can ruin your weekend—or worse, leave you stranded on the water. A pre-season inspection catches issues before they become problems.
Your pre-season checklist should include:
