Spring is here, and if you’re a Lake Granbury boat owner, that means one thing: it’s time to get your vessel ready for the water. But before you back that trailer down the ramp, a little prep work goes a long way toward protecting your investment and making sure your first day out is a great one — not a frustrating one.
We put together this checklist based on what we see at the shop every season. The boats that come in well-maintained are the ones that hold their value, run better, and look great year after year. The ones that don’t? They’re the ones needing expensive oxidation removal and restoration work that could have been avoided.
Here’s exactly what to do before boat season kicks off on Lake Granbury.
1. Inspect the Hull and Gelcoat
Start from the outside. Give your hull a thorough visual inspection, looking for:
- Cracks, chips, or spider cracks in the gelcoat
- Oxidation (a chalky, dull, or faded appearance)
- Water stains and scum lines from last season
- Any impact damage from storage or trailering
Oxidation is the most common issue we see on Lake Granbury boats, especially ones stored outdoors through the summer. Texas UV is brutal, and unprotected gelcoat fades fast. If you’re seeing significant dullness or chalking, a 1-step or 2-step oxidation removal service before the season starts will restore the finish and set you up for a protective coating that actually bonds properly.
Pro tip: Run your hand along the hull. If it comes away with a white or chalky residue, that’s oxidation — and it needs to be addressed before any wax or coating is applied, or you’re just sealing in the damage.
2. Detail the Exterior Before the First Launch
This is the step most boat owners skip, and it’s the one that makes the biggest difference. A proper exterior detail before the season includes:
- Hand wash to remove all winter storage grime, dust, and contaminants
- Decontamination to remove embedded minerals, hard water deposits, and surface buildup
- Polish to restore gloss and clarity to the gelcoat or fiberglass
- Protective coating or wax to seal and protect the surface for the season ahead
If your boat was detailed and coated last season, now is a good time to inspect the coating’s condition and apply a maintenance wash before getting back on the water.
3. Consider Marine Ceramic Coating for Long-Term Protection
If your boat isn’t already ceramic coated, spring is the best time to do it. Here’s why: a freshly detailed, contaminant-free surface is the ideal canvas for a coating application — and getting it done before the season means you’re protected from day one.
Marine ceramic coating (we use FEYNLAB HYDRO at our shop) creates a semi-permanent, hydrophobic barrier on your hull, gelcoat, vinyl, tower, and glass that:
- Repels water, lake grime, and algae
- Blocks UV rays that cause oxidation and fading
- Makes every wash dramatically faster and easier
- Protects the surface for years, not months
For Lake Granbury boat owners, this is a no-brainer. The combination of Texas sun, warm fresh water, and constant use means unprotected surfaces deteriorate quickly. A ceramic coating is the single best thing you can do to preserve your boat’s appearance and value long-term.
Pricing starts at $100 per linear foot for new or like-new boats. Book a consultation to get an accurate quote for your vessel.
4. Clean and Protect Interior Surfaces
The interior takes just as much abuse as the exterior — maybe more. Before the season:
- Vacuum and wipe down all vinyl seating — look for cracking, mildew, or staining from last season
- Clean all windows and glass inside and out
- Wipe down the dashboard, gauges, and electronics with appropriate cleaners
- Check carpet or flooring for mold, mildew smell, or water damage
- Treat vinyl surfaces with a UV protectant to prevent fading and cracking through the summer
If your vinyl is already cracked or heavily faded, it may be beyond a DIY fix — but for surfaces in decent shape, a good clean and UV treatment goes a long way.
5. Flush and Inspect the Engine
Detailing is our specialty, not marine mechanics — but we see enough boats to know that engine prep is non-negotiable before the season. At minimum:
- Change the engine oil and filter if it wasn’t done at winter storage
- Inspect the impeller (replace every 1–2 seasons as a standard practice)
- Check belts, hoses, and clamps for wear or cracking
- Flush the cooling system if it wasn’t flushed before storage
- Inspect the fuel system — check for water in the fuel, inspect fuel lines, and replace the fuel filter if needed
- Test the battery and charging system
If you’re not comfortable doing this yourself, get it to a marine mechanic before your first launch. A breakdown on Lake Granbury is no fun.
6. Check Safety Equipment
Texas Parks & Wildlife requires specific safety equipment on all vessels. Before you launch, confirm you have:
- Life jackets (PFDs) for every person on board, in serviceable condition
- Throwable flotation device (Type IV)
- Fire extinguisher — check the charge and expiration date
- Sound-producing device (horn or whistle)
- Navigation lights — test all of them
- Current registration and numbers properly displayed
7. Inspect the Trailer
The trailer is easy to overlook, but a trailer failure can ruin your day before you even hit the water:
- Check tire pressure and tread — trailer tires often develop flat spots and dry rot during storage
- Inspect wheel bearings — repack or replace if they weren’t serviced last fall
- Test all trailer lights (brake lights, turn signals, running lights)
- Check the winch strap and safety chains
- Inspect the bunks or rollers for wear
- Make sure the trailer hitch, coupler, and ball are secure and properly matched
8. Do a Pre-Launch Systems Check
Before you leave the driveway, run through this quick checklist:
- Drain plug is IN the boat (you’d be surprised)
- Bilge pump is working
- All gear is loaded and secured
- Fuel tank is topped off
- Kill switch lanyard is in place
- Phone is charged and you have a float plan
