Aluminum Fishing Boat Pre-Launch Checklist

A good day on the water starts before the boat ever leaves the driveway.

Taking a few minutes to inspect your aluminum fishing boat, trailer and equipment before every trip can catch simple problems while they’re still easy to fix.

A dead trolling-motor battery is annoying at home.

A flat trailer tire is inconvenient in the driveway.

A missing drain plug becomes considerably more interesting after you back down the ramp.

The Tin Can Boat Works Pre-Launch Checklist is designed for aluminum jon boats and V-hull fishing boats, but most of these checks apply to virtually any small fishing boat.

The goal isn’t to perform a complete mechanical inspection every time you go fishing.

It’s to develop a simple routine.

Boat. Motor. Power. Trailer. Safety. Gear.

Check them before you leave.

If those checks become habit, you’ll catch many of the problems that can ruin a fishing trip before the boat reaches the water.

Start With a Walk Around the Boat

Before hooking up—or before pulling away if the boat is already connected—walk around the entire rig.

Look at the boat.

Look underneath it.

Look at the trailer.

You’re looking for anything that changed since the last trip.

Maybe a tire looks low.

Maybe a tie-down isn’t connected.

Maybe something was left sitting on the casting deck.

Maybe the trolling motor wasn’t secured.

Maybe a compartment lid wasn’t latched.

This doesn’t need to take ten minutes.

A simple walk-around catches a surprising number of problems.

Check the Drain Plug

Yes, it deserves its own section.

Verify that the drain plug is installed before launching the boat.

Don’t rely on remembering that you installed it.

Look at it.

Touch it if necessary.

Confirm it.

If you normally remove the drain plug while the boat is stored, develop a routine that makes forgetting it difficult.

Some owners keep the plug attached near the drain opening when the boat is stored. Others place it somewhere they’ll physically encounter it while preparing the boat.

Whatever system you use, make it consistent.

Then check it again at the ramp.

Look Over the Hull

You don’t need to crawl underneath the boat before every fishing trip, but give the hull a quick visual inspection.

Look for:

  • New dents
  • Cracks
  • Damaged welds
  • Loose or damaged rivets
  • Obvious corrosion
  • Damage around the transom
  • Anything hanging below the hull
  • Evidence of impact since the previous trip

If the boat took a hard hit during the last outing, inspect that area more closely before returning to the water.

Small aluminum boats are durable.

That doesn’t mean damage should be ignored.

Check the Transom and Motor Mounting

Take a quick look at the transom, particularly if you’re running an outboard.

Check for:

  • Unusual movement
  • Loose mounting hardware
  • Cracks
  • Separation
  • Corrosion
  • Damage around mounting bolts

Make sure the outboard itself is securely mounted.

If anything looks different from the previous trip, investigate it before launching.

Check Your Fuel

It sounds obvious until you’re floating away from the ramp.

Make sure you have enough fuel for the trip, plus an appropriate reserve.

For portable tanks, check the tank, fuel line, fittings and primer bulb where applicable.

Look for:

  • Fuel leaks
  • Cracked hoses
  • Damaged fittings
  • Loose connections
  • Strong unexplained fuel odors

Fuel-system problems shouldn’t be ignored.

If you see or smell evidence of a leak, correct the problem before operating the boat.

Give the Propeller a Look

A quick propeller inspection can identify damage from the previous trip.

Look for:

  • Bent blades
  • Large nicks
  • Cracks
  • Fishing line around the propeller shaft
  • Other visible damage

Fishing line wrapped around a prop shaft can damage seals if it’s left there.

If you picked up line during the previous trip, don’t assume it fell off.

Check.

Check the Batteries

Modern fishing boats depend heavily on batteries.

You may have separate batteries for:

  • Starting
  • Trolling motor
  • Electronics
  • Accessories

Make sure they’re charged before leaving home.

Also check that batteries are properly secured and that terminals and connections aren’t loose.

Look for:

  • Corrosion
  • Damaged cables
  • Loose terminals
  • Swollen or damaged battery cases
  • Exposed conductors
  • Unusual heat damage

If your boat has an onboard charger, make unplugging and securing the shore-power cord part of your pre-departure routine.

Driving away while still connected to the charger is an avoidable way to start the morning.

Test Important Electrical Equipment

Turn on the equipment you’re likely to need.

Depending on the boat, that might include:

  • Navigation lights
  • Bilge pump
  • Fish finder
  • GPS
  • Trolling motor
  • Livewell
  • Horn
  • USB/12V outlets

You don’t necessarily need to operate everything extensively.

You’re confirming that critical systems power up before you get to the ramp.

Inspect the Trolling Motor

Make sure the trolling motor is properly secured for travel.

Check:

  • Mount
  • Locking mechanism
  • Propeller
  • Shaft
  • Wiring
  • Plug/receptacle
  • Foot pedal or remote

A trolling motor bouncing around while traveling isn’t good for the motor, mount or boat.

If you use a removable trolling motor, verify that its mounting hardware is properly secured.

Check the Trailer Tires

Trailer tires deserve more attention than they usually receive.

Before towing, check:

  • Tire pressure
  • Visible cracking
  • Bulges
  • Cuts
  • Unusual wear
  • Embedded objects
  • General condition

Don’t judge trailer tires only by tread depth.

Trailer tires often age out before they wear out.

Know the age of your tires and replace them when condition or age warrants it.

Don’t forget the spare.

A spare tire with no air isn’t much of a spare.

Check the Hubs and Bearings

Before leaving, look for obvious signs of trouble around the hubs.

After you’ve driven a short distance, especially before a longer trip, it’s also worth checking whether one hub feels significantly hotter than the others.

A developing bearing problem is much easier to address before it becomes a roadside failure.

Bearing inspection and service should also be part of your regular trailer-maintenance schedule.

Verify the Trailer Connection

Check the entire connection between the trailer and tow vehicle.

Confirm:

  • Coupler fully seated and locked
  • Correct hitch ball
  • Safety pin or coupler lock installed
  • Safety chains connected
  • Electrical connector attached
  • Trailer jack completely raised
  • Breakaway system connected where equipped

Then test the lights.

Check:

  • Running lights
  • Brake lights
  • Left turn signal
  • Right turn signal

Don’t assume they’re working because they worked last weekend.

Boat trailers and electrical connections live difficult lives.

Check the Winch and Tie-Downs

Before towing, make sure the boat is properly secured to the trailer.

Check:

  • Bow eye
  • Winch strap
  • Winch
  • Safety chain where equipped
  • Transom tie-downs

Inspect straps for cuts, fraying and deterioration.

A boat should be properly secured for highway travel—not simply resting on the trailer.

Check Your Safety Equipment

Requirements vary depending on boat, location and use, so owners should know and follow the applicable regulations.

At minimum, make sure the safety equipment required for your boat and passengers is actually aboard, accessible and in usable condition.

That may include:

  • Proper personal flotation devices
  • Throwable flotation device where required
  • Fire extinguisher where required
  • Sound-producing device
  • Navigation lights
  • Visual distress signals where required
  • Registration/documentation
  • Other locally required equipment

Don’t bury emergency equipment underneath a mountain of tackle where nobody can reach it.

Secure Fishing Gear

Fishing rods have an amazing ability to find trouble while traveling.

Before leaving:

  • Secure rods
  • Close tackle compartments
  • Latch storage lids
  • Secure coolers
  • Secure anchors
  • Store landing nets
  • Remove loose items from decks
  • Secure anything that could blow out

Pay particular attention to hooks and lures already tied onto rods.

A crankbait with exposed treble hooks bouncing around a boat during highway travel can make unloading considerably more exciting than necessary.

At the Ramp: Don’t Rush

Boat ramps create pressure.

Someone is waiting behind you.

Another boat is coming out.

Someone is backing down the ramp.

That’s exactly when simple things get forgotten.

Whenever possible, use the staging area to prepare the boat before entering the launch lane.

That’s where you should:

  • Confirm the drain plug
  • Remove transom straps
  • Prepare dock lines
  • Load remaining equipment
  • Remove motor supports where appropriate
  • Turn on the battery system as needed
  • Make sure passengers are ready
  • Verify the boat is ready to launch

Don’t use the ramp itself as your preparation area when a staging area is available.

Keep the Bow Attached Until You’re Ready

Don’t remove the bow winch strap too early.

Ramp angle, boat design and trailer setup can allow a boat to move unexpectedly once it’s no longer secured.

Prepare the boat, back down the ramp and release the boat at the appropriate point for your particular setup.

A little patience is much cheaper than watching your boat launch itself onto concrete.

Create the Same Routine Every Time

The most effective pre-launch checklist is the one you actually use.

Try to perform the checks in approximately the same order before every trip.

For example:

Walk around → boat → motor → batteries → trailer → safety gear → fishing gear → ramp preparation.

Repetition turns the checklist into habit.

Eventually, you’ll notice something is missing simply because a step in your routine doesn’t feel right.

One Final Check Before Launch

Before the boat enters the water, ask yourself:

Plug?

Fuel?

Battery?

Safety gear?

Motor?

Everything disconnected from the trailer that should be—and everything still connected that needs to be?

Then go fishing.

A few minutes of preparation can prevent hours of aggravation.

That’s what the Tin Can Boat Works Owner’s Guide is about: keeping small fishing boats simple, dependable and ready to use.
