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.

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. Learn how start isolation and dual-circuit battery switches keep the electronics on their own battery, how to find and test the start-only wire, and what to check after the job.

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.

Strange Engine Noises - What a Knock, Tick, Rattle, Whine, Grind or Squeal Can Mean

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.

Stripping Old Bottom Paint: Chemical Strippers, Blasting and Sanding

Learn when old bottom paint has to come off, how chemical strippers, soda or media blasting and sanding compare, how to protect yourself and the water from toxic dust, and why a bare hull needs primer or a barrier coat before new antifouling.

Switching to Lithium (LiFePO4) Boat Batteries: What Changes and When It's Worth It

What really changes when you swap lead-acid for lithium iron phosphate (LiFePO4) batteries on a boat: the battery management system, charger settings, protecting the alternator with a DC-DC charger, not mixing chemistries, cold-weather charging, and which jobs (trolling, house, starting) suit lithium. House-bank conversions should be designed and installed by a qualified marine electrician.

Synthetic Teak Decking: Choosing, Installing and Caring for PVC Teak

PVC "teak" such as Flexiteek, PlasDECK and Permateek gives you the teak look without oiling or recaulking, but it is glued down for good and it gets hot in the sun. Learn how it compares with real teak and foam, what a pro or DIY install involves, and how to clean, repair and keep the warranty valid.

Taking Delivery of a New Boat: Dealer PDI, Paperwork, Sea Trial and First Service

What to check before you sign for a new boat: the dealer's pre-delivery inspection, the HIN and title paperwork, warranty registration, required safety gear, a systems walk-through and a real sea trial. Then break the engine in properly and book the first service so the warranty stays intact.

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.

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.

Tilting an Outboard or Sterndrive by Hand: Using the Trim Manual Release Valve

When the power trim quits, a small release valve on the trim unit lets you raise or lower the motor by hand, so you can get off a sandbar, load the trailer or get home. Learn where to find it, how far to open it, how to lift and support the motor safely, and why it must be closed again before you run.

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.
