Repair & maintenance guides

How to Inspect and Replace Boat Fuel Fill and Vent Hoses

Old fill and vent hoses crack, go soft and leak gasoline into the bilge, often where you can't see them. Learn the signs of aging, which USCG hose types (A1, A2, B1, B2) belong on fill and vent lines, why fill hoses need two clamps at each end, how to check the vent fitting, flame arrester and anti-spill devices, and how a careful replacement is done.

How to Inspect and Replace Sacrificial Anodes (Zincs)

Check the anodes on your outboard, sterndrive or inboard running gear, replace them when they are half gone, and choose the right metal for the water you boat in. Fresh anodes are cheap insurance against expensive corrosion damage to your lower unit, drive and prop.

How to Inspect and Replace Spark Plugs

Pull, read and replace the spark plugs on a gas outboard, sterndrive, inboard or PWC. Fresh, correctly gapped plugs help the engine start easily and run smoothly, and the old plugs tell you a lot about the engine's health.

How to Inspect and Replace Your Bow Eye and Transom Eyes

Check the bow eye and transom tie-down eyes for rust, loose nuts and missing backing plates, and replace and reseal them properly, because a failed bow eye can let the boat slide off the trailer.

How to Inspect and Troubleshoot Hydraulic and Electric Trim Tabs

Keep your trim tabs working with a simple seasonal check of the blades, anodes, fluid, lines and wiring, and track down the usual faults when a tab won't move, only one side works, or the tabs stay stuck down.

How to Inspect and Use the Trailer Winch, Strap, Tie-Downs and Safety Chains

Check the winch, strap or cable, bow safety chain, transom tie-downs and the safety chains to your vehicle, and learn how each one is meant to be used. These parts keep the boat on the trailer and the trailer behind your truck.

How to Inspect Boat Trailer Axles, Leaf Springs and Hangers

Check the parts that actually hold your boat off the road: the axle tube, leaf springs, hangers, shackles, bushings and U-bolts (or the rubber torsion axle on newer trailers). Learn what rust-through, broken leaves and worn shackles look like, how uneven tire wear points to a bent axle, and when it's time to replace instead of patch.

How to Inspect Wakeboard Tower, T-Top and Bimini Hardware

Towers, T-tops and biminis carry tow ropes, speakers, boards, electronics and wind loads, all on a handful of bolts. Learn how to check the welds, bases, backing plates, bolts, folding hinges and accessory loads before a crack or a loose bolt becomes an accident.

How to Inspect Your Boat's Fuel Tank, Fill, Vent and Hoses

A leaking gas tank is one of the most dangerous problems a boat can have, and it usually starts out of sight. Learn how to inspect portable and built-in tanks, spot aluminum tanks corroding from below, know the ethanol risk for old fiberglass tanks, and check the fill, vent, hoses, clamps and sender, plus why tank replacement is a job for a pro.

How to Inspect, Inflate and Replace Boat Trailer Tires

Check your trailer tires the way the pros do: the right type (ST), the right load range, the right cold pressure, and an honest look at their age. Tires are the number one reason boat trailers end up on the side of the highway.

How to Install (and Remove) a Keel Guard on a Trailer Boat

An adhesive keel guard protects the bow and keel line of a trailer or beaching boat from sand, rocks and ramps. Learn when it's worth it, how to prep and apply one the way the maker intends, and how to take it off later.

How to Install a Backup Bilge Pump and High-Water Alarm

Add a second, larger automatic bilge pump mounted above the primary, with its own overboard discharge and a loud high-water alarm wired so it works even with the battery switch off, then test it every month so it buys you real time if the boat starts taking on water.

How to Install a Boat Radar Antenna (Radome or Open Array)

Plan and install a radar the right way: choose a mounting spot high enough and clear of obstructions, keep the beam above people's heads, give an open array room to spin, bolt it down with backing plates, route the cable without damaging it and seal every deck pass-through. Know when the job belongs to a certified installer.

How to Install an Inspection Port (Deck Plate) in a Deck or Bulkhead

Add a screw-out or pry-out deck plate so you can reach hidden nuts, wiring, hoses and through-hulls, or check a deck core for rot. Learn where it is safe to cut, how to pick and size the port, how to seal a cored deck with epoxy, and how to bed the ring so it never leaks.

How to Install and Set Up Forward-Facing (Live) Sonar

Mount a live sonar transducer such as Garmin LiveScope, Lowrance ActiveTarget or Humminbird MEGA Live on your trolling motor or a pole, give it clean power, route the cable so it survives stow and deploy, and dial in the basic settings. Most "bad picture" and "dead transducer" problems trace back to one of these steps.

How to Install EVA Foam Decking (SeaDek-Style Pads) on Your Boat

Closed-cell foam decking makes a hard fiberglass deck grippy and comfortable underfoot. Learn when a peel-and-stick DIY job makes sense, how to template, cut and prep, the temperature and gap rules, how to lay pads without trapped air, and how to clean, repair and eventually remove them.

How to Keep a Boat Maintenance Log and Organize Your Receipts

Set up a simple maintenance log that records the date, engine hours, work done, parts and who did it, and keep receipts and photos organized. Good records help with warranty and insurance claims, show buyers the boat was cared for and reveal wear patterns before something fails.

How to Keep Mice and Rodents Off Your Stored Boat

Mice love a stored boat: dry, quiet and full of soft nesting material and tasty wire insulation. Learn how to remove what attracts them, close their way in, choose deterrents and traps that actually work, avoid the risks of poison, and check the wiring safely in spring.

How to Keep Your Boat Fridge, Freezer or Icebox Cold (and Off Your Batteries' Back)

Most boat fridge problems are not a dead compressor: they are trapped heat, low voltage, leaky seals or too much frost. Learn the owner checks for air-cooled, water-cooled and keel-cooled units, how to estimate power draw, and how to store the system for winter.

How to Keep Your Boat in the Water Over Winter (De-Icers, Covers and Checks)

Wintering afloat can be safe if you still winterize every water system, keep the bilge pump and batteries working, use a de-icer correctly on a GFCI-protected circuit, respect the shock and thin-ice risks, and visit the boat regularly.

How to Launch and Retrieve Your Boat Alone

A repeatable routine for putting a trailer boat in and taking it out by yourself: what to do in the staging area, how to rig one long line so you can control the boat from the dock, when power loading is off-limits, and the safety habits that keep you, your boat and the next boater out of trouble.

How to Link a Kicker Motor to Your Main Engine With a Tie Bar

Steer your kicker from the helm by linking it to the main outboard with a tie bar: choose a fixed, adjustable or cable-type kit that fits your steering, align it so the motors track together, fit a quick-release, check for binding at every turn and tilt position, and use it only the way the kit maker allows.

How to Load Your Boat Safely: Capacity Plate, Balance and Stability

Too much weight, or the right weight in the wrong place, is behind most small-boat capsizes and swampings. Learn to read the capacity plate (persons, weight and horsepower), add up your real load, balance it side to side and fore and aft, and adjust for rough water, water aboard and towing riders.

How to Maintain an Anchor Windlass and Inspect and Mark Your Anchor Rode

Keep your electric windlass working with a seasonal clean-and-grease, sort out a dead or slow windlass from the breaker and solenoid to the motor, and inspect, mark and splice your chain and rope rode. Your anchor is a safety system; this guide keeps every link of it ready.
