Texas winters are milder than most, but "milder" doesn't mean freeze-proof. North Texas still sees hard freezes every year — often in January and February, sometimes as early as late November — and one overnight freeze is all it takes to crack an engine block, split a water line, or ruin a battery. Winterizing your boat before putting it into storage is cheap insurance. Here's how to do it right.
Old oil holds acids and moisture that corrode internal engine parts over months of sitting. Change the engine oil and filter before storage, not after. While you're at it, top off the fuel tank (a full tank leaves less room for condensation) and add a quality fuel stabilizer, then run the engine for a few minutes so the stabilized fuel works through the whole system. Stabilizer only protects fuel that's actually reached the engine.
Salt water and lake water both leave deposits. Flush the engine with fresh water using earmuffs or a flushing kit until it runs clear. Then drain every water system on the boat:
Water left in a line expands when it freezes, and a split line discovered in spring is an expensive way to start boating season.
Spray fogging oil into the carburetor or throttle body while the engine runs, then pull the spark plugs and give each cylinder a shot of fogging oil. This coats the cylinder walls against rust during months of sitting. Grease the outdrive or lower unit fittings, check the gear lube for any milky appearance (which means water intrusion and a seal that needs attention), and inspect the prop for dings you can address over the winter.
Batteries self-discharge in storage, and a fully discharged battery in a cold snap is often a dead battery for good. Remove the battery, clean the terminals, and store it on a smart trickle charger or maintainer somewhere it won't freeze. Check the charge level monthly. Boat batteries aren't cheap — a $40 maintainer beats a $200 replacement every time.
Wash the hull and deck, then apply a coat of wax — it makes spring cleanup far easier and protects the gel coat. Clean the interior thoroughly and remove anything edible; mice and insects find stored boats fast. Leave compartments and hatches cracked open for airflow, and toss in moisture-absorbing packs to fight mildew. If your boat lives on a trailer, inspect the trailer now so maintenance doesn't ambush you in April:
A quality fitted cover keeps rain, leaves, and UV off your boat, and it's the minimum protection you should give it. But North Texas hail doesn't care about a canvas cover, and neither does blowing debris in a spring storm. Enclosed or covered storage is the real upgrade: no sun beating on the upholstery all winter, no hail risk, and far less freeze exposure than an open driveway.
That's exactly what we built Godley RV & Boat Storage for. Our Godley, Texas facility offers covered and enclosed storage for boats and RVs, plus self storage units for all the gear that piles up in the garage over winter — life jackets, tackle, skis, the extra cooler collection. It's an easy drive from Cleburne, Burleson, Granbury, and the southwest Fort Worth side, so dropping the boat off and picking it up in spring doesn't eat a whole day.
Winterize the boat right, park it under cover, and spring launch will take an afternoon instead of a repair bill. Call us at (817) 709-5407 to reserve a covered or enclosed spot before the winter rush fills them up.
