Repair & maintenance guides

Taking Your Boat to Another State: Registration Reciprocity, Visitor Time Limits and Nonresident Permits

Your home-state registration lets you boat in other states, but only for a while, and some states add their own visitor permits, use-tax permits and invasive species stickers. Learn how federal reciprocity works, real examples from Texas, Florida, Washington and Oregon, and a checklist for a vacation trip or a season away. General information, not legal advice.

Taking Your Boat to the Bahamas: Cruising Permit, Fishing Permit, Passports, Radio License and Insurance

A paperwork checklist for running a US recreational boat to the Bahamas: the Bahamas cruising and fishing permits and their current fees, passports, the FCC ship station license, insurance navigation limits, pets, and the US 'skin on the fillet' rule for bringing Bahamian fish home. General information, not legal advice; fees and rules change often.

Teak Deck and Trim Care: Clean, Oil, Seal or Leave It Natural

Keep teak decks, rails and trim looking good without wearing them away. Choose between a natural gray look, oil, sealer or varnish, and learn how to clean teak gently so you don't destroy it with harsh cleaners or a pressure washer.

Testing Engine Coolant: Test Strips, Refractometer or Lab Analysis

Coolant can look perfect and still be worn out. Learn how to test the coolant in a closed-cooled inboard, sterndrive, diesel or generator with test strips, a refractometer or a mail-in lab kit, what each result tells you, and when the answer is a coolant change or a call to a mechanic.

Testing Your VHF Antenna and Coax: Radio Checks, SWR, Connectors and Mounts

Most weak or scratchy VHF radios have nothing wrong with the radio. Learn how to test the whole antenna system, from a proper radio check and a DSC test call to a multimeter and SWR meter, how to find corroded connectors and wet coax, and when to replace the cable, antenna or mount.

The Pre-Departure Safety Briefing: What to Tell Every Passenger (with a Printable Checklist)

A five-minute talk before you leave the dock turns guests into a crew that can help in an emergency. Cover life jackets, the engine cut-off switch, the fire extinguisher, how to call for help on the VHF, what to do if someone falls overboard, staying seated, seasickness and carbon monoxide near the stern, then use the printable checklist every trip.

The Real Cost of Owning a Boat: Building a Yearly Budget and Cutting Costs with DIY

Add up what a boat really costs each year (storage, insurance, fuel, maintenance, winterizing, registration, depreciation and the surprise repair), check it against the common rules of thumb, and find the places where do-it-yourself work and smarter choices save real money. Practical planning help, not financial advice.

Tow Ropes, Tubes and Watersports Gear: Inspect, Rig and Retire

Check ski, wakeboard and tube ropes, handles, towable tubes and your boat's tow points before every outing, rig them the right way, and know when to throw gear out. Includes the safety basics (spotter, flag, life jackets, prop and carbon monoxide) that vary from state to state.

Tow Vehicle Maintenance for Boat Owners (Transmission, Differential, Brakes, Hitch)

Keep the truck or SUV that pulls your boat ready for the job: follow the severe-service schedule, protect the transmission from heat, check the rear differential for ramp water, keep brakes, tires, hitch and wiring in shape, and rinse salt off the underside after every saltwater launch.

Tow Vehicle Rear Differential Care: Ramp Water, Milky Gear Oil and Limited-Slip Additive

Backing the truck's rear axle into the water at the launch ramp can pull water into the differential through its vent. Learn how water gets in, how to keep the axle dry, how to drain and read the gear oil, why limited-slip axles need friction modifier, when to change the fluid, and when the differential needs a shop.

Towable Tube Care and Repair: Find Leaks, Patch the Bladder and Know When to Retire It

Inspect a towable tube's bladder, cover, valves, handles and tow point, find and patch leaks the right way, and dry and store it so it lasts. Also covers rider ratings and the damage that means the tube should be retired, not repaired.

Towing a Wide or Heavy Boat: Width Limits, Oversize Permits and When to Hire a Hauler

In most states a boat or trailer wider than 8 feet 6 inches (102 inches) is a wide load that needs a permit, and some loads also need flags, signs, lights, set travel hours or escorts. Learn how to measure your rig, find each state's rules, get the permits and decide when a professional transporter makes more sense.

Trailer Tongue Jack and Coupler Care: Grease, Adjust and Know When to Replace

The tongue jack and coupler take a beating from weight, road grit and launch-ramp dunking. A few minutes of cleaning and grease a couple of times a season keeps the jack cranking smoothly and the coupler locking tight on the ball, and tells you when either part is worn out.

Type I and II Treatment Systems (Electroscan, Purasan, Lectra/San): Care, Salt, Tablets and Winter

A flow-through treatment system lets a boat discharge treated waste where the law allows, but only if it works and only outside no-discharge zones. Learn how these units work, why salt and tablets matter, how to keep electrodes and dispensers clean, how to lock the system in a no-discharge zone, and how to lay it up dry for winter.

Underwater LED Lights: Care, Leaks, Corrosion, Wiring and the Rules

Keep underwater LED lights bright and your hull dry. Learn the difference between through-hull and surface-mount lights, how to clean growth off the lens without damaging it, what to check for leaks, wiring, fusing and bonding, when the boat has to be hauled, and why the lights should not be on while you're underway.

Upgrading Boat Trailer Hubs: Grease-Through Spindles, Oil Bath, Protectors and Pre-Packed Kits

Choose the right hub setup for how you use your trailer, swap in a pre-packed hub kit, adjust it correctly and know when the axle itself is the real problem. Better hubs mean fewer roadside bearing failures and less time with greasy hands.

USCG Documentation Renewal: When, How, What It Costs and How to Avoid Look-Alike Renewal Mailers

Keep your boat's Coast Guard Certificate of Documentation current: how long a recreational certificate lasts (1 to 5 years), the federal fee schedule, renewing directly with the NVDC online, what happens if it lapses, why many states still want registration and a decal, and how to spot the third-party letters that charge several times the real fee.

USCG Required Safety Equipment Check by Boat Length

Walk through your boat and confirm you carry every piece of safety gear the US Coast Guard requires for your boat's length and type, and that none of it is expired or worn out. Missing or expired gear is one of the most common tickets on the water, and it is the gear you need when things go wrong.

Used Boat Paperwork: Titles, Liens, HIN Checks, Bill of Sale and Registration

A practical checklist for the paperwork side of buying a used boat: state title or Coast Guard documentation, checking for liens and theft, verifying the hull ID number, writing a proper bill of sale, the trailer's own title, registering in your name, and transferring warranties and checking recalls. Rules vary by state, so confirm each step with your state agency.

Used Boat Purchase Agreement and Closing: Deposit, Contingencies, Bill of Sale and Who Pays What

A plain-English walk-through of buying a used boat on paper: getting ready before you offer, what the purchase and sale agreement should say, how the deposit is held and when it comes back, survey, sea trial, financing and insurance contingencies, paying off the seller's loan, the bill of sale, closing and transferring the paperwork, and the costs each side usually covers. Practical help, not legal advice; rules vary by state.

V-Drive Transmission Care for Wake and Ski Boats: Fluid, Cooler, Coupler and Shaft Seal

Wake boats and many ski boats put the engine in the stern, backward, and turn the power through a V-drive transmission. Learn how to check and read the transmission fluid, why the cooler and its drain matter in winter, what the coupler and shaft seal tell you, and which noises and leaks mean it's time for a technician.

Vapor Lock and Hot Restarts: Why Your Boat Won't Start After a Stop on a Hot Day

On hot days, fuel can boil into vapor in the lines, carburetor or fuel system after you shut down, so the engine cranks but won't start, or starts and dies after a fuel stop. Learn how to recognize heat soak, restart a hot engine the right way, and reduce the problem with fuel choices, ventilation and line routing.

Vinyl Hull Wraps: Pros, Cons, Prep, Care and Removal

Find out whether a vinyl wrap makes sense instead of paint for your hull, how to prep for it, when to hire an installer, how to wash it without ruining it, and why wraps stop at the waterline.

Visual Distress Signals: Flare Expiry, Storage, Practice and Safe Disposal

Make sure your flares, smoke signals, distress flag or electronic distress light meet the Coast Guard rules for day and night, are not past their 42-month date, and are stored where you can grab them. Then get rid of expired flares the safe and legal way instead of letting them pile up in a locker.
