Whether your boat has suddenly broken down or you’re looking to prevent costly repairs before they happen, Seas The Day provides comprehensive boat repair and maintenance services for recreational boat owners throughout Phoenix, Scottsdale, Peoria, Glendale, Lake Pleasant, and surrounding Arizona communities.
Our technicians maintain one of Arizona’s largest commercial rental fleets, giving us daily experience diagnosing and repairing the same issues that affect private boat owners. From routine maintenance to complex engine diagnostics, our goal is to identify the root cause of the problem, perform quality repairs, and help you avoid future breakdowns.
Whether your engine won’t start, is running rough, overheating, losing power, or displaying warning alarms, our technicians diagnose and repair a wide variety of engine problems affecting outboards, inboards, and sterndrives.
Every repair begins with testing, not assumptions. We inspect the systems affecting engine performance before recommending repairs, allowing us to solve the actual problem instead of simply replacing parts.
We commonly repair:
Our goal is simple: restore your boat to dependable, long-term reliability.
The most expensive boat repairs usually begin as inexpensive maintenance items.
A worn impeller can become an overheated engine.
An old fuel filter can lead to injector damage.
A weak battery can leave you stranded at the dock.
Routine maintenance helps prevent these failures while extending engine life, improving reliability, and reducing long-term ownership costs.
Our preventative maintenance services include:
Because Arizona’s extreme heat accelerates wear on many marine components, preventative maintenance is one of the best investments you can make in your boat.
Marine electrical systems operate in harsh conditions where heat, water, vibration, and corrosion can create problems that are difficult to diagnose.
Our technicians inspect and repair electrical issues throughout your boat to restore reliable operation and improve safety.
Our electrical repair services include:
Proper marine-grade electrical repairs help prevent recurring problems and improve long-term reliability.
Fuel system issues are one of the most common causes of poor engine performance in Arizona.
Extreme temperatures, ethanol-blended fuel, contaminated gasoline, and long storage periods can all contribute to starting issues, hesitation, stalling, and reduced power.
Our technicians diagnose and repair:
If your boat loses power under load or struggles to accelerate, the fuel system is often one of the first areas we inspect.
Boat engines overheat when the cooling system can no longer circulate enough water to maintain safe operating temperatures.
Ignoring an overheating engine can quickly lead to major engine damage.
We inspect and repair:
Common signs of cooling system problems include:
Routine cooling system maintenance is especially important for boats operating in Arizona’s extreme summer temperatures.
Safe boating depends on responsive steering and smooth throttle and shift controls.
If your steering feels stiff or your controls aren’t responding properly, it’s important to have the system inspected before returning to the water.
Our steering and control services include:
Properly functioning controls improve both safety and the overall boating experience.
The lower unit transfers power from your engine to the propeller and is one of the hardest-working components on your boat.
Routine inspections help prevent expensive drivetrain failures.
Our lower unit services include:
If you notice milky gear oil, vibration, grinding noises, or shifting issues, your lower unit should be inspected promptly to prevent further damage.
Arizona’s boating season places unique demands on every boat. Months of storage followed by continuous summer use can accelerate wear on engines, batteries, fuel systems, and cooling components.
Seasonal service helps prepare your boat before boating season begins and keeps it running reliably throughout the year.
Our seasonal maintenance includes:
Preparing your boat after winter storage with inspections, fluid changes, battery testing, cooling system checks, and engine diagnostics.
Inspecting high-use boats during peak boating months to identify wear before it becomes a breakdown.
Protecting your boat during storage while reducing repair costs before next season.
Whether you boat every weekend or only a few times each year, seasonal maintenance helps maximize reliability, improve safety, and extend the life of your boat.
We service many recreational boats including:
• Pontoon boats
• Deck boats
• Fishing boats
• Speedboats
• Party barges
If you are unsure whether we can service your boat, contact us and we can review the details.
We service boats from 1990 or newer.
If your boat has a discontinued engine, we may still be able to perform repairs if you provide the necessary replacement parts.
