Repair & maintenance guides

Crossing Inlets and Bars Safely: Tide Timing, Coast Guard Bar Restrictions and When Not to Go

Inlets and river bars are where calm-looking days turn deadly. Learn why an ebb tide against an ocean swell builds breaking waves, how to check bar reports and Coast Guard restrictions, how to read the inlet before you commit, how to run it with life jackets on, and when to wait or go somewhere else.

Diesel Cabin Heaters: What a Forced-Air or Bulkhead Heater Install Involves

Understand what goes into installing a diesel cabin heater (fuel pickup, exhaust or chimney, combustion air, ducting, power and CO alarms) so you can plan it with an installer, check the work, and keep the heater safe with monthly runs and regular service.

Docking in Wind and Current: Read the Conditions, Use Spring Lines and Know When to Go Around

Wind and current decide most docking jobs. Learn to watch your drift before you commit, approach into the stronger force, set fenders and lines with a clear crew plan, use a spring line to pin the boat to the dock, handle single and twin engines, and back out to try again before it turns into a collision.

Dogs and Pets Aboard: A Safety Checklist for Boat Owners

Set your boat and your dog up for a safe day on the water, from a well-fitted pet life jacket with a handle to shade, fresh water, safe boarding and a plan for getting a dog back aboard if it goes over the side.

Drain Plugs: Types, Pre-Launch Checks, Spares and Replacing a Garboard Drain

A forgotten or worn drain plug is one of the most common ways a boat floods at the ramp. Learn the plug types, a launch routine that makes it hard to forget, how to look after plugs and fittings, how to replace a garboard drain, and when the plug should come out for storage.

ELCI Retrofit: Adding Whole-Boat Shock Protection to an Older Boat

What an ELCI (equipment leakage circuit interrupter) is, why ABYC now requires one on new boats with shore power, what a retrofit involves and costs, and what to do when one trips. You plan, test and troubleshoot; an ABYC-certified marine electrician does the wiring.

Electric and Hydraulic Headsail Furlers: Care, Manual Override and Safety

Keep a powered headsail furler working with simple care: furl the right way, rinse the swivels, check the wiring, breaker and switches, and practice the manual override before you need it.

Electric Linear Actuators on Boats: Kicker Lifts, Towers, Hatches, Tables and Seats

Electric actuators raise kicker brackets, fold wake towers, lift engine hatches and move tables and helm seats. Learn how they work, why water and side load kill them, how to fuse and test one directly on 12 volts, and how to replace one safely.

Electric Marine Toilet Troubleshooting: Won't Flush, Weak Flush, Won't Stop Filling

Electric and macerating marine heads fail in a handful of predictable ways. Work from the cheapest checks to the messiest ones to fix a toilet that won't run, flushes weakly, trips its breaker, keeps filling, loses or gains water in the bowl, or backs up, and learn what to keep out of it.

Electric-Over-Hydraulic and Electric Trailer Brakes: Controller Setup, Breakaway and Care

Why most boat trailers use surge or electric-over-hydraulic (EOH) brakes instead of plain electric drums, how to pick a compatible in-cab brake controller and set its gain, how to test the breakaway switch and battery, and how to keep the system working around saltwater.

Electrical Safety at Your Private Dock or Boat Lift: GFCI, Shock Drowning and Annual Checks

Lights, outlets, lift motors and de-icers at a home dock put household current right next to the water, and a hidden fault can kill a swimmer without any warning. Learn the owner checks you can do safely, the protection your dock should have, the no-swimming rule, and which jobs must go to a licensed electrician.

Electronics That Reset or Shut Off When You Start the Engine: Finding and Fixing Voltage Sag

If your chartplotter, fishfinder, VHF or stereo blinks off or reboots when you crank the engine or switch on a big load, the cause is almost always low voltage reaching the device. This guide walks from the cheapest checks (battery, connections, grounds) to the real fixes: a dedicated electronics feed, start isolation between batteries, and voltage-stabilizing converters.

Emergency Drills for Your Crew: Engine Failure, Fire, Steering Loss and Man Overboard

Practice what everyone aboard does when the engine quits, a fire starts, the steering fails or someone falls in. A few short drills each season turn panic into a plan, and teach your crew to anchor, call for help on VHF 16 or DSC, and get a tow.

Emergency Steering: What to Do When Your Boat's Steering Fails

A plan for the day the wheel goes slack or locks up - stop safely, find the problem, then steer home with an emergency tiller, twin engines, a drogue or a bridled bucket - plus how to build the gear and practice it before you need it, on outboard, sterndrive and inboard boats.

Engine Cut-Off Switch (Kill Switch) and Lanyard: The Law, Testing and Daily Use

How the engine cut-off switch (ECOS) and its lanyard or wireless fob work, when federal law requires you to wear it (boats under 26 feet, 3 hp or more, on plane), how to test it before every trip, and why a spare clip aboard matters.

Engine Hour Meters: Why Hours Matter, How to Verify Them and How to Replace a Meter Honestly

Engine hours set your service schedule and a big part of your boat's resale value. Learn the difference between analog meters and engine-computer hours, how to verify the real hours on a used boat, and how to replace a dead or broken meter while keeping an honest record of the old hours.

EPIRB and PLB Care: Registration, Batteries, Self-Test and Mounting

Keep your 406 MHz emergency beacon ready to work on the worst day of your life. Register it free with NOAA and renew every two years, track the battery and hydrostatic release dates, run the self-test without triggering a false alert, and know what happens after you press the button.

Epoxy and Two-Part Paint Safety: How to Avoid Becoming Allergic

Epoxy and isocyanate-cured paints can make you allergic for life, sometimes after many jobs with no problem at all. Learn how sensitization happens, which gloves and clothing to wear, how to get epoxy off skin without solvents, when you need a respirator, and how to handle sanding dust and leftovers safely.

Ethanol (E10) Fuel Care: Stabilizer, Phase Separation, Fuel Lines and Tank Vents

Keep E10 gasoline from damaging your boat engine. Learn how to use stabilizer, test for water and phase separation, and inspect the fuel lines, primer bulb, anti-siphon valve and tank vent. Most fuel-related breakdowns start with one of these.

Extended Warranties and Service Plans for Boat Engines: Factory Plans vs Third-Party Contracts

Decide whether an extended service plan is worth it: how factory plans such as Mercury Product Protection and Yamaha Y.E.S. differ from third-party contracts, what they usually cover and exclude, why maintenance records decide claims, how deductibles, transfers and cancellations work, and the questions to ask before you sign. Practical guidance, not legal or financial advice.

FCC Ship Station License vs. a Free MMSI: Which One Your Boat Needs, and How to Keep It Current

Most U.S. recreational boats that stay in U.S. waters don't need an FCC radio license, but every DSC radio and AIS needs a registered MMSI. Learn when an FCC ship station license and operator permit are required (foreign ports, SSB/HF, satellite), how to get an MMSI from BoatUS, America's Boating Club or Shine Micro, and what to do when you sell, buy or rename a boat.

Financing a Boat: Loan Terms, Survey and Insurance Requirements, Liens and the True Cost of Ownership

Understand a boat loan before you sign: typical terms and down payments, what lenders check, why they want a survey and insurance, how the lien is recorded (Coast Guard preferred mortgage for documented boats, state title for the rest), how the payoff works when you sell, and how to add up the real yearly cost beyond the monthly payment. Practical guidance, not financial advice.

Fixing a Sagging Cabin Headliner: Re-glue, Battens or Replace

Find out why cabin headliners sag, when a quick re-glue is worth trying, how wood battens make a lasting fix, and how to replace fabric, vinyl or panel liners safely with good ventilation and without drilling through the deck.

Flybridge and Upper-Deck Safety: Weight Up High, Rails, Ladders and CO

People and gear on a flybridge, tower or pontoon upper deck raise the boat's center of gravity and cut its reserve stability. Learn how many to allow up top, how to check rails, gates, ladders and hardtop or tower loads, how to get crew down safely in rough water, and why carbon monoxide can collect at the stern and even on the bridge.
