Saltwater Outboard Care: The After-Every-Trip and Monthly Routine
A simple routine that keeps salt from eating your outboard, built from Honda, Yamaha, Mercury and Suzuki advice. It covers flushing after every trip, washing, where to spray anticorrosion (and where never to), monthly greasing, anodes, and tilting up or storing out of the water.

Salvage and Branded Title Boats: What They Mean, the Risks, and How to Check Before You Buy
Understand boats that an insurer declared a total loss: what salvage, rebuilt and hull-damaged title brands mean, why flood and storm boats hide expensive problems, how branded titles affect insurance, financing and resale, how to dig into a boat's history, and what a survey should check. Title branding rules differ a lot by state, and some states don't brand boat titles at all.

Satellite Internet on Your Boat: Starlink Plans, Mounting, Power and Wiring
An owner's guide to putting Starlink aboard: which plans allow coastal, offshore and in-motion use (as of October 2026), how much battery it eats, 12-volt versus inverter power, where to mount the dish, and how to route and seal the cable without leaks.

Satellite Messenger vs PLB vs EPIRB: Which Emergency Device Should You Carry?
A PLB or EPIRB calls government search and rescue through the 406 MHz Cospas-Sarsat satellites with no subscription; a satellite messenger like an inReach or SPOT sends an SOS through a private network and adds texting and tracking for a monthly or yearly fee. Learn how each one alerts rescuers, what registration, subscriptions and batteries they need, what to carry for lakes, coastal and offshore boating, and how to test without causing a false alarm.

Seasickness: How to Prevent It and Care for Seasick Crew and Guests
Almost anyone can get seasick in the right conditions, but a few habits make a big difference. Learn why it happens, where to sit, what to eat and drink, how over-the-counter remedies fit in (and why the person running the boat must be careful with drowsy ones), how to look after someone who's sick, and when it might be something more serious. General information only, not medical advice.

Selling Your Boat: Broker, Private Sale, Consignment or Dealer Trade-In
Compare the four ways to sell a used boat (yacht broker, selling it yourself, dealer consignment and trade-in) on cost, effort, speed and risk, then handle the listing agreement, buyer scams, sea trial and survey etiquette, deposit and closing the right way. Practical help, not legal or financial advice.

Set Up Your VHF Radio: MMSI, DSC, GPS Hookup and Radio Checks
Get a free or low-cost MMSI number, program it into your DSC radio, connect your GPS so a distress alert sends your exact position, check the antenna, and learn the Channel 16 rules and the right way to do a radio check.

Sharing a Boat: Co-Ownership Agreements, Partnerships and Boat Club Alternatives
How to share a boat without losing a friend: choosing a partner, what a written agreement should cover (shares, costs, scheduling, maintenance standards, insurance, title, decisions and the exit), how to handle the inevitable disagreements, and when a boat club, rental or peer-to-peer option makes more sense. Practical guidance, not legal or tax advice.

Shipping a Boat with a Professional Transporter: Quotes, Vetting, Prep and Claims
Most boat shipments go fine, but when they don't, the owner who checked the carrier's authority and insurance, prepped the boat properly and documented everything at pickup and delivery is the one who gets paid. Here's how to hire a transporter, prepare the boat and handle damage.

Shock-Absorbing Boat Seats and Pedestals: Choosing, Installing and Adjusting
Pounding through chop hurts backs and necks, and hard wave impacts can fracture a spine, especially up front. Learn the difference between a shock-absorbing pedestal and a suspension seat base, how to mount one solidly, how to set it for the rider's weight, and the simple care that keeps it working, plus the seating and driving habits that matter just as much.

Shore Power Adapters and Y-Splitters: When a 30A or 50A Adapter Is Safe, and When It Isn't
Pigtail adapters and Y-splitters let a boat plug into a pedestal that doesn't match its inlet, but the wrong one, or the right one used carelessly, can overheat, trip the marina's ground-fault protection or start a fire. Learn the difference between 30A 125V, 50A 125V and 50A 125/250V, which adapters are reasonable, how to keep loads safe, and how to check connections for heat.

Shore Power Cord Ends: How to Judge a Cord, and When to Replace the Plug or the Whole Cord
Burned blades, a hot plug or a cracked locking ring don't always mean a brand-new cord, but sometimes they do. Learn how to inspect a shore power cord and its ends, decide between a replacement end and a new cord, what a proper sealed marine connector looks like, which parts of the job are safe for an owner and when the work belongs to an ABYC-certified electrician, plus the habits that make cord ends last.

Shore Power Inlet and Cord Upgrades: Burned Plugs, Better Connectors and Safe Adapters
Why shore power plugs and boat inlets overheat and burn, how to spot an inlet that needs replacing, what newer connector designs offer, and how to choose, size and care for cords and adapters. You inspect and buy the right cord; an ABYC-certified marine electrician replaces the inlet and its wiring.

Shore Power Safety: Cords, Inlets, Burned Plugs and Electric Shock Drowning
An owner's inspection routine for your shore power cord, plugs, boat inlet, galvanic isolator and ground-fault protection, plus the right way to plug in and the facts about Electric Shock Drowning. This guide is for looking and testing only; any electrical repair belongs to an ABYC-certified marine electrician.

Small Portable Outboard Care (2.5 to 20 hp Kickers and Dinghy Motors)
Keep your dinghy motor or kicker starting on the first few pulls. Use fresh fuel, flush it, run the carburetor dry before you put it away, carry and lay it down on the correct side so oil doesn't flood the cylinders, and check the shear pin or prop, gear oil and engine oil on schedule.

Smoke and Heat Detectors on a Boat: Where They Make Sense, What to Buy and How to Test
A fire in a closed cabin, engine room or lazarette can grow for minutes before anyone notices. Learn where smoke alarms and heat detectors make sense aboard, why boats are hard on household alarms, how to power and test them, how they fit with CO alarms, and how automatic engine-room extinguishers and engine shutdown tie in.

Spiders, Wasps and Insects on Your Boat: Prevention and Safe Cleanup

Spring Commissioning - Getting Your Boat Ready for the Season
Wake your boat up after storage with a step-by-step check of the battery, fuel system, engine, drive and safety gear. Catching a cracked hose or dead battery in the driveway beats a tow on opening weekend, and saves a typical shop commissioning fee.

Spun Prop Hub - How to Tell, Quick Marker Test and Repair Options
If the engine revs up but the boat barely accelerates, the rubber or plastic hub inside your propeller may be slipping. Learn how a spun hub feels, how to confirm it with a simple marker test, the difference between pressed rubber hubs and replaceable hub kits, and your repair options.

Start Isolation for Your ACR: Stop the Chartplotter and Stereo from Rebooting at Engine Start
If your plotter, radio or stereo reboots every time you turn the key even though you have two batteries and an automatic charging relay, the relay may be tying the house battery into the cranking dip.

Stiff or Seized Mechanical Steering - Lubricate, Inspect and Replace the Steering Cable
Fix hard, notchy or loose cable steering on an outboard boat. Find out whether the engine, the tilt tube, the cable or the helm is the problem, clean and grease what can be serviced, and measure and install a new cable correctly when the old one is done.

Storing a Boat on Stands and Blocks: Keel Blocking, Stand Placement and Safety Chains
Learn how a boat should sit on keel blocks and boat stands for winter or a haul-out, so you can check the yard's work, spot dangerous setups, and keep your boat from settling, distorting or falling over in wind, rain or a storm.

Learn what common boat engine noises often point to, which ones mean shut down now, and the safe checks you can do yourself before describing the problem to a mechanic.

Stress and Spider Cracks in Fiberglass, Cosmetic or Structural?
Learn what causes spider, stress and hairline cracks in your boat's gelcoat, how to tell cosmetic crazing from a structural problem with a simple tap and flex check, and when a gelcoat repair is enough or a pro is needed.
