Engine Service, Plus Materials

Engine Installation

Installing a new engine is one of the most important upgrades you can make to your boat, and it requires precision, experience, and adherence to manufacturer standards. At Racine Riverside Marine, our engine installation service is designed to ensure your new outboard, I/O, or sterndrive is mounted, aligned, and connected properly for long-term performance. We handle the entire process with the care and accuracy your investment deserves.

A professional installation begins with preparing the boat for the new engine—removing old components, inspecting mounting surfaces, and verifying that fuel, electrical, and control systems are ready for connection. Our technicians then perform the installation according to manufacturer specifications, ensuring proper alignment, secure fastening, and clean rigging throughout the system. Attention to detail at this stage ensures smooth operation and protects your engine’s warranty.

Once installed, we complete a thorough inspection and functional test to confirm everything operates as it should. Controls are calibrated, electrical systems are verified, and the engine is evaluated for correct startup and response. With expert installation, you can count on reliable performance, improved handling, and the confidence that your new engine is ready for the water.

Engine Check & Tune Ups

For new engines, the 20-hour check is one of the most important early services you can schedule. This initial inspection ensures that your engine has broken in correctly and that all components are operating as the manufacturer intended. At Racine Riverside Marine, we perform this service with precision, following brand-specific guidelines to protect your warranty and support long-term engine health.

During the 20-hour check, our technicians evaluate key systems that experience the most adjustment during early operation. This includes inspecting the lubrication system, checking for proper cooling flow, reviewing throttle and shift linkages, and verifying that all fasteners and connections remain secure. We also replace the engine oil and filter, as early hours often produce residual break-in material that should be removed to maintain clean operation. Completing the 20-hour check helps ensure smooth performance, improved reliability, and a strong foundation for the life of your engine. It’s a simple but essential step that protects your investment and prevents small issues from developing into larger concerns. If your boat is approaching its first 20 hours, our team is ready to get your engine dialed in for the seasons ahead.

A proper tune-up keeps your engine running efficiently and reduces the risk of mid-season issues that could cut your time on the water short. At Racine Riverside Marine, our tune-up service focuses on restoring optimal performance by inspecting and adjusting the components that directly affect reliability, fuel efficiency, and smooth operation. It's a straightforward service that delivers noticeable improvements to how your boat feels and responds. During a tune-up, our technicians review ignition components, fuel delivery systems, filters, spark plugs, and other key parts that experience wear over time. Any components nearing the end of their lifespan are replaced with high-quality parts that meet manufacturer standards. This careful approach ensures your engine starts easily, runs cleanly, and maintains consistent power.

Oil Change

Whether you’re preparing for the season or addressing performance concerns mid-year, a tune-up is one of the simplest ways to keep your engine healthy. It’s an important step in preventative maintenance and a reliable way to extend the life of your motor while ensuring every trip on the water starts with confidence.

Routine oil changes are one of the simplest yet most important steps in keeping your engine healthy. Fresh, clean oil helps reduce friction, control temperature, and prevent internal wear—allowing your engine to run smoothly and reliably throughout the season. At Racine Riverside Marine, we perform oil changes using manufacturer-approved oils and filters to ensure the best possible protection for your outboard, I/O, or sterndrive.

Our technicians begin by inspecting the condition of the existing oil and filter, which can reveal early signs of engine concerns such as contamination or improper combustion. After draining the engine, we install a new filter and refill the system with the correct grade and quantity of marine oil. This careful process helps maintain proper lubrication and ensures your engine is prepared for the demands of regular operation. Staying consistent with oil changes improves performance, reduces long-term maintenance costs, and extends the life of your engine. Whether you're preparing for a busy boating season or simply staying ahead on routine service, our team provides quick, reliable oil changes that keep your vessel running at its best.

Engine Repower

Repowering is exactly what it sounds like: getting a new and better power source behind your boat. Whether that is by rebuilding your engine or installing a new one, this cost-efficient option is a great alternative to purchasing a new boat or continuing expensive maintenance on an aging engine. There are many reasons that people choose to repower their boat. Buying a new boat may not be in your budget at the moment or you may simply want a better, more powerful or fuel efficient engine.

When your boat’s performance no longer matches your expectations, repowering can offer the benefits of a new vessel without the cost of replacing the entire boat. At Racine Riverside Marine, our repower service provides a modern, efficient engine that brings new life to your boat—improving reliability, fuel efficiency, and overall enjoyment on the water. Whether your current engine is aging, underperforming, or simply outdated, repowering is a smart, long-term upgrade.

Repowering transforms the way your boat feels and performs. Owners often experience quicker starts, smoother operation, quieter running, and significantly better fuel economy. With a professionally installed modern engine, your boat becomes more dependable and enjoyable—extending its useful life and enhancing every trip on the water. If you’re considering a major upgrade, our team is ready to guide you through the repower process from start to finish.
