Protecting Your Investment: Exterior and Interior Care
Protecting the exterior and interior of your Suncatcher or G3 keeps it looking great and performing well for years. Consistent care after each trip is the key to maintaining your boat’s value and preventing major headaches on Lake Texoma or Table Rock Lake.
Exterior and Hull Ski Boat Maintenance Tips
Your boat’s exterior takes a beating from sun and water, but keeping it in showroom condition is manageable with the right approach.
Washing after every use is the most important habit. A quick rinse with fresh water and marine-grade soap removes salt, dirt, and algae that can damage your boat’s finish.
Your waxing schedule should be three times per season (beginning, middle, and end). Marine wax acts like sunscreen, protecting against UV damage and corrosion while maintaining shine. Avoid waxing in direct sunlight or on non-skid surfaces.
Gelcoat polishing is needed when your boat’s finish looks dull from oxidation. A good polish before waxing can restore its original luster.
Don’t forget cleaning non-skid surfaces. A stiff brush and specialized cleaner will remove trapped dirt without damaging the texture.
Metal corrodes five times faster in saltwater than in freshwater. Regular care of all metal parts is essential to prevent costly replacements. Metal corrosion facts
Saltwater vs. Freshwater Care
Your maintenance routine depends on where you boat. Saltwater is more corrosive and demands extra vigilance.
| Feature | Freshwater Maintenance | Saltwater Maintenance |
|---|---|---|
| Engine | Flush engine after every use to remove debris. | Critical: Flush engine with freshwater for at least 10 minutes after every use to remove salt. |
| Hull | Wash hull after every use; inspect for algae. | Wash hull after every use; inspect for barnacles and salt buildup. Waxing helps. |
| Exterior | Rinse all surfaces with fresh water. | Rinse all exterior surfaces (tower, hardware, trailer) with fresh water to remove salt. |
| Metal Parts | Regular cleaning and inspection for rust. | Frequent: Inspect and clean all metal components for corrosion. |
| Anodes/Zincs | Inspect annually or as needed. | Crucial: Inspect sacrificial anodes (zincs) frequently and replace when 50% depleted. |
| Trailer | Rinse off dirt and debris. | Essential: Rinse the entire trailer with fresh water after every saltwater launch. |
| Interior | Wipe down and dry to prevent mold/mildew. | Wipe down and dry, paying attention to salt residue on upholstery. |
The bottom line: Saltwater requires immediate cleaning after every outing. With freshwater, you have more flexibility, but cleaning sooner is always better.
Interior Upholstery and Carpet Care
Keeping your boat’s interior clean and comfortable ensures everyone enjoys their time on the water.
Wipe down vinyl seats after each trip with mild soap and water to prevent stains from sunscreen and dirt. Use a damp sponge, not poured water.
Mildew prevention is critical. Ensure everything is completely dry before covering your boat. Tackle any mildew spots immediately with a vinegar solution or marine-specific cleaner.
UV protectant spray is like anti-aging cream for your vinyl. Apply it regularly to prevent fading and cracking from the sun’s harsh rays.
Vacuum carpets regularly to remove sand and dirt. If carpets get soaked, dry them completely to prevent mold and odors.
These ski boat maintenance tips protect your investment and keep your boat a welcoming place for your family.
Your Complete Guide to Seasonal Ski Boat Maintenance Tips
Seasonal ski boat maintenance tips are key to separating reliable boats from weekend headaches. Whether preparing for a spring trip to Lake Texoma or winterizing your Suncatcher, proper timing is crucial. Most problems arise from skipping small but vital checks that can prevent a tow back to the dock or costly freeze damage.
Before & After Every Trip Checklist
These simple checks take just minutes but prevent the majority of on-water breakdowns.
Before you launch:
- Ensure the drain plug is secure.
- Check that all safety gear is aboard and accessible (life jackets, fire extinguisher, distress signals). The Coast Guard offers free vessel safety checks. Get a free vessel safety check
- Run the bilge blower for at least 4 minutes before starting the engine to vent fumes.
- Check engine fluid levels (oil, coolant, power steering).
- Test your bilge pump and visually inspect the hull.
After every outing:
- Wipe down all surfaces to remove water spots, dirt, and salt residue.
- Flush your engine after every use, even in freshwater, to remove minerals and debris.
- Cover your boat to protect it from UV rays and weather.
Mid-Season and Annual Inspections
Deeper inspections help catch developing problems. We recommend these checks mid-season and annually, especially for boats that see heavy use on lakes like Table Rock.
- Hoses and clamps: Look for rust, wear, and loose connections.
- Engine mounts: Ensure all bolts are tight and secure to prevent vibration.
- Bilge pump and float switch: Test both components to ensure they activate properly.
- Electronics: Test all navigation equipment, depth finders, and entertainment systems. Check for damaged cables and clean connections.
- Steering and throttle cables: Address any stiffness or grinding sounds immediately. Proper lubrication is key.
- Propeller and drive system: Inspect for damage, check sacrificial anodes (zincs), and clear debris from through-hull fittings. These components on your Suncatcher, G3, or Lowe work hard and need regular attention. More info about Tigé boats (for comparison)
Preparing for Winter Storage (Winterization)
In Oklahoma and Missouri, proper winterization is essential to prevent catastrophic freeze damage. Water expands when it freezes, which can crack an engine block.

- Remove and store batteries: Store batteries in a cool, dry place on a smart charger or maintainer to extend their life.
- Clean the boat: Clean the interior and exterior thoroughly, ensuring everything is dry to prevent mildew.
- Cover the boat: Use a quality, breathable boat cover or consider professional shrink-wrapping for maximum protection.
Spring Prep (De-Winterization)
Proper de-winterization ensures your first trip of the season to Table Rock Lake is a success.
- Reconnect the battery: Ensure terminals are clean and connections are tight.
- Check all fluid levels: Top off oil, coolant, and other fluids. Spring is a great time for an oil change if you didn’t do one in the fall.
- Inspect the water pump impeller: Replace it if there are any signs of wear.
- Check belts and hoses: Look for wear or damage that may have occurred during storage.
- Test all systems: Before launching, run the engine on a flush kit and test all electrical systems, lights, and steering.
- Inspect the trailer: Check tire pressure, grease wheel bearings, and test brakes and lights.
Safety First: Preventing Sinking and Trailer Mishaps
No one wants their G3 or Suncatcher at the bottom of Lake Texoma. Yet, for every boat that sinks underway, four sink at the dock. Repairs can cost 40% of the boat’s value. The good news is that most sinkings are preventable with proper ski boat maintenance tips and awareness.
Why Boats Sink and How to Prevent It
When a boat sinks at the dock, the question isn’t about the bilge pump, but where the water came from. Understanding the common causes is key to protecting your investment.
- Failed Underwater Fittings: Half of all dockside sinkings are due to failed fittings like stuffing boxes, thru-hulls, or outdrive bellows. Your Lowe or G3 has several of these critical points.
- Rain and Snow: These account for 32% of sinking claims. An open hatch or poorly fitted cover can let in enough water to overwhelm a bilge pump.
- Bilge Pump Issues: A bilge pump can mask a slow leak, giving false confidence. Keep your bilge clean and test the pump and float switch regularly.
- Thru-Hull Fittings: Every fitting below the waterline needs a working seacock (shutoff valve). Inspect fittings and hoses for wear or corrosion. Always double-clamp hoses below the waterline.
- I/O Drive Bellows: Inspect these rubber components several times a season for cracks. Storing the outdrive down helps prevent failure.
- Drain Plugs: A forgotten drain plug is a common and preventable cause of sinking. Make checking it part of your pre-launch ritual.

Essential Boat Trailer Maintenance
Your boat trailer works hard getting your Suncatcher or G3 to Table Rock Lake. A highway breakdown is dangerous and expensive.
- Tires: Check pressure and tread condition before every trip, including the spare.
- Lights and Wiring: Test all lights (running, brake, turn signals) before each trip. Look for frayed wiring and cracked lenses.
- Wheel Bearings: Use bearing protectors to check and add grease. Have bearings professionally repacked annually or every few thousand miles.
- Brakes: If your trailer has hydraulic brakes, check the fluid level regularly and replace the fluid every two years.
- Winch Strap and Safety Chains: Inspect the winch strap for fraying and ensure safety chains are securely attached and undamaged.
- Bunks/Rollers: Check for worn carpet or damaged rollers that could scratch your boat’s hull.
