Caring for Your Avalon Pontoon Boat: Essential Maintenance Tips for Performance & Longevity
There’s something magical about cruising on a pontoon boat—the smooth glide, the open deck, the laughter of friends and family echoing across the water. But here’s the truth: your Avalon pontoon won’t keep delivering those perfect days unless you show it some love and attention.
Why Regular Pontoon Maintenance Matters More Than You Think
Your Avalon pontoon is an investment, and like any investment, it needs protection. Pontoon boats face unique challenges—constant water exposure, sun damage, and the wear-and-tear of docking and trailering. The good news? A little preventive care goes a long way. Regular maintenance doesn’t just extend your boat’s lifespan; it keeps you safe on the water and saves you from costly repairs down the road.
I learned this lesson the hard way when a friend ignored a small crack in his pontoon tube. What started as a minor issue turned into a $3,000 repair. Don’t be that person.
Understanding Your Pontoon’s Vital Components
Before we dive into maintenance routines, let’s talk about what makes your Avalon tick. Your pontoon tubes (those aluminum cylinders keeping you afloat) are the heart of your boat. Then there’s the deck, which takes constant abuse from foot traffic and sun exposure. Your motor needs regular attention to run smoothly, and the upholstery and Bimini top require protection from UV rays and mildew.
Each component demands different care, but nothing too complicated. Think of it like maintaining a car—consistent small tasks prevent big headaches.
Cleaning Your Pontoon: More Than Just Aesthetics
Let’s start with the basics: cleaning. After every outing, give your Avalon a good rinse with fresh water. This removes salt, dirt, and organic material that can cause corrosion and staining. A quick 10-minute rinse after each trip can prevent hours of scrubbing later.
For deeper cleaning, use a marine-grade soap like Star brite Boat Wash or 3M Marine Boat Soap. Avoid household cleaners—they’re too harsh and can damage your boat’s finish. Work from top to bottom, and don’t forget the pontoon tubes. Algae and scum build up quickly on those underwater surfaces.
Here’s a tip I picked up from a marina owner: use a soft-bristle brush for the tubes and a microfiber cloth for the deck and vinyl. The brush gets into textured surfaces without scratching, while microfiber won’t leave lint behind.
Protecting Your Investment: Seasonal and Ongoing Care
Upholstery and Canvas: Fighting Sun and Mildew
Your Avalon’s vinyl seats and Bimini top face two enemies: UV radiation and mildew. UV rays break down vinyl, causing fading and cracking. Mildew thrives in damp, shaded areas.
Fight back with these steps:
- Clean vinyl seats monthly with a marine vinyl cleaner like 303 Aerospace Protectant Vinyl Cleaner
- Apply UV protectant after cleaning—products like 303 Aerospace Protectant create a barrier against sun damage
- Remove canvas covers when storing your boat to allow air circulation
- Use mildew-resistant spray like Star brite Mildew Stain Remover on canvas before storage
“Protecting your upholstery isn’t vanity—it’s about preserving resale value. A pontoon with pristine seats can command $2,000 to $3,000 more than one with cracked, faded vinyl.”
Engine Maintenance: Keep That Motor Humming
Whether you’ve got a Yamaha, Mercury, or Honda outboard on your Avalon, engine care is non-negotiable. Never skip your scheduled oil changes—most manufacturers recommend changing oil every 100 hours or annually, whichever comes first.
Check your lower unit oil regularly. This lubricant protects your gears from water intrusion and friction damage. If it looks milky or has a metallic sheen, you’ve got water contamination and need immediate service.
Fuel system care is equally important. Add a fuel stabilizer like STA-BIL Marine Formula before storage to prevent ethanol-related problems. Ethanol attracts water, which leads to phase separation and engine damage. Old fuel is the number one cause of outboard problems—don’t let it happen to you.
Pontoon Tube Care: Your Foundation Needs Attention
Those aluminum tubes are tough, but they’re not indestructible. Inspect them regularly for:
- Dents and dings from docking impacts
- Corrosion spots where the protective coating is compromised
- Loose baffles (you’ll hear them rattling inside the tubes)
- Leaks indicated by waterlogging or reduced buoyancy on one side
Touch up any scratches or chips in the anodized coating immediately with marine-grade aluminum paint. Exposed aluminum oxidizes quickly, especially in saltwater environments.

Trailer Maintenance: Don’t Forget What Gets You There
Your Avalon spends plenty of time on its trailer, so that trailer needs care too. Check wheel bearings annually and repack them with marine grease. Inspect tire pressure before every trip—underinflated tires cause blowouts and poor fuel economy.
Look for rust spots on the frame and treat them immediately with rust converter and touch-up paint. Galvanized trailers resist corrosion better, but they’re not immune. Lubricate the winch mechanism regularly so you’re not struggling to load your boat after a long day.
Winterization: Preparing for the Off-Season
If you’re in a cold climate, proper winterization is critical. Freezing water expands and can crack engine blocks, damage pumps, and destroy plumbing. Here’s your winterization checklist:
- Run fuel stabilizer through the entire system
- Fog the engine with fogging oil to prevent internal corrosion
- Drain all water from the engine, livewell, and freshwater system
- Remove batteries and store them on a trickle charger
- Cover the boat with a properly fitted cover that allows ventilation
Many boat owners skip the fogging step, but it takes five minutes and can prevent thousands in engine damage.
Frequently Asked Questions About Avalon Pontoon Care
How often should I wax my pontoon boat? Wax your Avalon’s deck and gelcoat surfaces 2-3 times per season using a marine-grade wax like Meguiar’s Marine Paste Wax. This protects against UV damage and makes cleaning easier.
Can I use a pressure washer on my pontoon? Yes, but keep the pressure under 1,500 PSI and maintain at least 12 inches distance from surfaces. High pressure can damage decals, strip sealant, and force water into electrical components.
What’s the best way to remove water spots from aluminum tubes? Use a mixture of white vinegar and water (50/50 ratio) or a dedicated aluminum cleaner like Star brite Aluminum Cleaner. Apply with a soft cloth and rinse thoroughly.
How do I know if my pontoon tubes are leaking? Signs include: one side riding lower than the other, reduced speed and handling, gurgling sounds inside tubes, or visible water inside access hatches. Get professional inspection immediately if you suspect leaks.
Should I cover my pontoon boat when it’s not in use? Absolutely. A quality mooring cover or storage cover protects against UV damage, bird droppings, tree sap, and weather. Make sure it’s properly vented to prevent mildew buildup.
How long do pontoon boats typically last? With proper maintenance, an Avalon pontoon can easily last 20-30 years. The aluminum tubes are incredibly durable, and most wear occurs in replaceable components like upholstery and canvas.
What maintenance can I do myself versus what needs a professional? DIY-friendly tasks include cleaning, waxing, upholstery care, and basic inspections. Leave engine internal work, welding, and electrical troubleshooting to certified marine technicians.
Your Pontoon Deserves the Best
Caring for your Avalon pontoon doesn’t require mechanical genius or endless hours—just consistency and attention to detail. Create a maintenance schedule, stick to it, and your boat will reward you with years of reliable performance and happy memories on the water.
Remember, the best time to fix a problem is before it becomes one. Always inspect your boat before heading out, keep your maintenance products stocked, and don’t ignore warning signs like unusual noises, performance changes, or visible damage.
