Why Maintenance Matters for Your Avalon
You bought an Avalon pontoon boat because you wanted quality, style, and reliability. The good news is that Avalon builds boats to last. The better news is that with proper care, your boat will outlast your expectations.
Avalon’s construction philosophy emphasizes durability. Their Reinforced Aluminum Pontoons, Multi-Chamber Floatation Design, and Premium Marine Vinyl Seating are all chosen to withstand the marine environment. But even the best materials need attention.
Think of maintenance as an investment, not a chore. Every hour you spend caring for your boat saves you hours of repair work down the road.
Here’s what Avalon themselves say about their construction: “From the very first boat, we set out to build the highest quality product on the water . . . At Avalon, we don’t just build boats—we create vessels that deliver unmatched quality and enduring value for the boating lifestyle you love.”
Are you treating your Avalon like the premium investment it is?
The Evolution of Pontoon Boat Maintenance
Pontoon boat care has evolved alongside the boats themselves. Here’s how maintenance practices have changed:
1970s-1980s
Basic aluminum pontoons with minimal maintenance needs. Owners focused on engine care; pontoons were left raw and often oxidized.
1990s
Vinyl seating became standard, introducing new cleaning requirements. Boat owners began using specialty marine products.
2000s
Clear-coated and polished pontoons emerged, requiring specific care to maintain shine. Pressure washers became common—sometimes too common.
2010s
LED lighting, touchscreen electronics, and advanced audio systems added electrical complexity. Owners needed to understand corrosion prevention.
Today
Modern Avalon boats feature sophisticated materials that reward proper care—and punish neglect. Specialized cleaning products and professional detailing services are widely available.
Weekly Maintenance: The 15-Minute Routine
If you only do one thing for your boat, make it this weekly routine. Fifteen minutes after every outing saves hours later.
Fresh Water Rinse
After every trip—especially in salt or brackish water—rinse the entire boat with fresh water. This includes:
- The pontoons (top and bottom)
- The engine (lower unit and cowling—never spray directly into the air intake)
- The trailer (if applicable)
- Any exposed metal fittings
Use a garden hose with a spray nozzle. Avoid pressure washers—they force water into places it shouldn’t go.
Wipe Down Vinyl
Your Premium Marine Vinyl Seating is durable, but water spots and sunscreen residue will stain if left to bake in the sun.
Use a microfiber cloth and a mild marine vinyl cleaner to wipe down all seating surfaces. Pay special attention to seams, where dirt collects.
Quick Check
Walk around your boat and look for:
- Loose screws or fittings
- Cracks in vinyl
- Unusual water in compartments
- Anything that doesn’t look right
This five-minute inspection catches small problems before they become big ones.
Drain Plugs
Make sure all drain plugs are removed and stored where you can find them. Water left standing in compartments leads to mold and mildew.
Pontoons: The Foundation of Your Boat
Your pontoons do the heavy lifting—literally. Keeping them in good condition is essential for performance, efficiency, and resale value.
Cleaning Aluminum Pontoons
Aluminum pontoons naturally develop a layer of oxidation over time. It’s harmless, but it dulls the shine. Some owners like the look of clean, bare aluminum. Others prefer a polished, mirror-like finish.
For basic cleaning:
- Use a mild detergent and a soft brush
- Avoid abrasive pads—they scratch the aluminum
- Rinse thoroughly
For heavy oxidation:
Avalon’s own Technical Information recommends specific cleaners based on your pontoon’s finish :
- Painted pontoons: Use only mild soap and water. Harsh chemicals will damage the paint.
- Polished pontoons: Use aluminum polish and a buffer to restore shine. Avalon’s testing found that Sharkhide Metal Protectant works well for maintaining the polished finish after cleaning.
- Raw aluminum pontoons: You can use acid-based cleaners like Star Brite Aluminum Cleaner or Aluma Brite to remove oxidation. Follow the instructions carefully—these are powerful chemicals.
“The single best thing you can do for aluminum pontoons is keep them clean and dry. Water spots left to sit become water spots that won’t come off without serious effort.”

Pressure Washer Warning
Never use a pressure washer on your pontoons, especially near welds. High-pressure water can force its way into seams and weld points, causing leaks that are expensive to repair.
Waxing
If your pontoons are painted or clear-coated, waxing them with a marine-grade wax protects the finish from UV damage and makes future cleaning easier.
How do your pontoons look right now? If they’re dull or chalky, it’s time for some attention.
Marine Vinyl Care: Protecting Your Interior
Your boat’s seating is one of the first things people notice—and one of the most expensive things to replace. Treat it right.
The Golden Rules of Vinyl Care
Clean spills immediately. Sunscreen, bug spray, and food are all enemies of marine vinyl. Sunscreen is especially damaging—it can cause permanent staining and even breakdown of the vinyl material.
Use the right products. Household cleaners like bleach, Windex, and Armor All will damage marine vinyl. Use products specifically designed for marine vinyl.
Don’t let it bake. When your boat isn’t in use, use the Integrated Bimini Top System or cockpit cover to protect vinyl from UV exposure. The sun is the slow killer of all marine materials.
Weekly Cleaning Routine
- Mix mild soap (like Dawn dish soap) with warm water
- Use a soft brush or microfiber cloth
- Scrub gently, paying attention to seams
- Rinse thoroughly with fresh water
- Dry with a soft cloth to prevent water spots
Deep Cleaning
For stubborn stains, use a dedicated marine vinyl cleaner. Products like 303 Marine Vinyl Cleaner or Star Brite Vinyl Cleaner are formulated to clean without damaging the material.
Vinyl Protectants
After cleaning, applying a vinyl protectant like 303 Aerospace Protectant adds a layer of UV protection and makes future cleaning easier. Avoid products with silicone—they can make vinyl slippery and attract dirt.
When was the last time you gave your vinyl seats a deep clean? If you can’t remember, it’s probably time.
Engine and Mechanical Systems
Your outboard engine is the heart of your boat. Regular maintenance keeps it running smoothly and prevents expensive failures.
Oil Changes
Most outboard engines need an oil change every 100 hours or once per season, whichever comes first. Use the oil grade recommended in your owner’s manual.
Lower Unit Gear Lube
The lower unit needs its gear lube changed annually. This lubricates the gears inside the lower unit and prevents water from entering through the propeller shaft seals. Milky-looking oil means water has gotten in—address this immediately.
Fuel System
Modern ethanol-blended fuels can cause problems if left sitting. Use a fuel stabilizer like Sta-Bil Marine Formula in every tank, especially if the boat will sit for more than a few weeks.
Replace your fuel filter (often called a water-separating filter) annually. Water in fuel is one of the most common causes of engine problems.
Propeller Inspection
Check your propeller for nicks, dings, and fishing line wrapped around the hub. Even small damage affects performance and fuel efficiency.
Steering and Controls
Check hydraulic steering fluid levels periodically. A soft or spongy feel at the helm means you need to add fluid or bleed the system.
Electrical System and Battery Care
Modern Avalon pontoon boats come with sophisticated electrical systems. LED Navigation and Deck Lighting, Advanced Helm Control Panels, Built-In Audio and Entertainment Systems—all of these rely on a healthy electrical system.
Battery Maintenance
- Keep terminals clean and coated with dielectric grease to prevent corrosion
- Check water levels in lead-acid batteries monthly
- Use a smart charger when the boat is stored for more than a week
- Consider a dual-battery setup if you run a lot of electronics
Corrosion Prevention
Marine environments are tough on electrical connections. Inspect terminals and connectors periodically. If you see green or white corrosion, clean it with a wire brush and apply dielectric grease.
The Stereo Switch
Avalon boats often have a dedicated music on/off dash switch. Even when the stereo itself is off, some models draw power if this switch is left on. Make it a habit to turn it off when you’re done for the day.
Is your battery dead at the start of the season? Leaving that stereo switch on over the winter is probably why.
Seasonal Maintenance: Spring and Fall
Spring Commissioning
After winter storage, your boat needs a thorough once-over before hitting the water:
- Battery: Charge and test. Replace if weak.
- Engine: Inspect belts and hoses. Check oil and gear lube. Replace water pump impeller every 2-3 years.
- Fuel system: Add fresh fuel if the tank wasn’t stabilized. Check for leaks.
- Safety gear: Check expiration dates on flares. Test fire extinguisher gauge. Inspect life jackets.
- Trailer: Check tire pressure, bearings, lights, and winch strap.
Winter Storage
Proper storage protects your boat during the off-season:
- Indoor storage: Ideal if available. Keeps your boat out of sun and snow.
- Outdoor storage: Use a high-quality cover. Elevate the tongue so water drains off. Consider shrink-wrapping for long-term outdoor storage.
- Engine winterization: Follow your owner’s manual. For outboards, this usually means changing lower unit oil, fogging the cylinders, and stabilizing fuel.
- Battery: Remove and store indoors on a smart charger.
- Vinyl: Clean thoroughly and store with cushions slightly separated to prevent mildew.
Avalon-Specific Maintenance Notes
Avalon provides detailed technical information for their boats. Here are some key points from their documentation:
Vinyl Care Protocol
Avalon’s official Technical Information includes a section on vinyl care :
- Clean spills as soon as they happen
- Use only mild soap and water for regular cleaning
- Avoid harsh chemicals like acetone or bleach
- Use vinyl protectants to maintain UV resistance
- Keep vinyl dry when not in use—mildew needs moisture to grow
Electrical System Notes
Avalon’s documentation warns that some stereo models have active components that may drain the battery even when the stereo switch is off . This is why that dedicated switch exists—use it.
Fuse Ratings
Never exceed factory fuse ratings . Each circuit is protected for a reason. Installing equipment that draws more power than the circuit can handle creates a fire risk.
