The Essential Boat Parts and Marine Hardware Checklist for Canadian Boaters
Share
Small parts cause big problems. A cracked impeller or a failed fuse can end your day on the water. Far from shore, it can also put you at risk.
This essential boat parts checklist shows what to keep on board and at home. It covers engine spares, fuel parts, electrical items and deck hardware.
Steveston Marine has supplied boat parts in Canada since 1941. With 10,000+ products, we help boaters stay ready for the most common repairs.
Quick Answer: Every boat should carry a spare impeller, fuel filter, spark plugs or injector parts, fuses, a spare propeller and prop nut, hose clamps, marine tape, and a basic tool kit. Keep deck hardware like cleats, shackles and hinges in good repair.
Why Every Boat Needs a Spare Parts Kit
Think of a spare parts kit like a first-aid kit for your boat. You hope you never need it. When you do, it saves the day.
In Canada, many boaters travel far from help. On the BC coast, the next marina can be hours away. A small kit lets you fix common problems and get home safely.
Engine Parts to Keep on Board
Your engine is the heart of your boat. These spares handle the most common engine problems.
• Impeller: Pumps cooling water. A failed impeller causes overheating fast.
• Spark plugs: Keep a full set for gas engines.
• Drive belts: For inboards and sterndrives.
• Thermostat and gasket: For cooling system repairs.
• Engine oil: At least one top-up bottle.
• Gear lube: For quick lower unit top-ups.
The impeller is the most important spare of all. Keep one for every engine. Shop our raw-water pump impellers by engine make and model.
Warning sign: A weak tell-tale stream or a rising temperature gauge often means the impeller is failing.
Fuel System Parts
Bad fuel is one of the top causes of engine trouble. These parts help you fix it on the water.
• Spare fuel-water separator filter
• Spare inline fuel filter
• Primer bulb for outboards
• Fuel line and hose clamps
• Fuel stabilizer for long storage
Tip: Change your fuel filter at least once a season. Water in fuel is common in damp Canadian weather.
Propeller and Running Gear
A damaged prop can leave you stranded or cause heavy vibration. Rocks, logs and deadheads are common in Canadian waters.
• A spare propeller that fits your engine
• A spare prop nut, washer and cotter pin
• A prop wrench
• Spare anodes for your drive or shaft
We stock boat propellers for every engine, in aluminum and stainless steel.
Electrical Parts and Supplies
Saltwater and damp air are hard on wiring. Small electrical faults are among the most common problems on boats.
• Assorted marine fuses
• Spare bulbs for navigation lights
• Heat-shrink connectors and crimp tool
• Marine-grade wire
• Electrical tape
• Corrosion inhibitor spray
• Battery terminals and cable ties
Tip: Use marine-grade, tinned wire. It resists corrosion far better than regular wire.
Plumbing and Bilge Parts
Water should stay outside your boat. These parts keep pumps and hoses working.
• Spare hose clamps in several sizes
• A short length of spare hose
• Bilge pump or float switch
• Seacock plugs (soft wood bungs) for each through-hull
Safety note: Tie a wood bung beside every through-hull. If a fitting fails, you can plug the hole fast.
Deck and Marine Hardware
Deck hardware takes heavy loads every day. Loose or corroded fittings can fail when you need them most.
The core marine hardware every boat needs includes:
• Cleats: For docking and anchoring.
• Shackles and snap hooks: For anchors, fenders and lines.
• Hinges and latches: For hatches, lockers and doors.
• Eye straps and pad eyes: For tie-downs and fender lines.
• Rails and fittings: For safety and grab points.
• Stainless steel fasteners: Screws, bolts and washers.
Check your boat cleats and deck hardware each season for cracks, rust and loose bolts.
Tip: Always use 316 stainless steel in saltwater. It resists rust better than lower grades.
Your Onboard Tool Kit
Parts are only useful if you can fit them. Keep a small, waterproof tool kit with:
• Screwdrivers (flat and Phillips)
• Adjustable wrench and socket set
• Pliers and wire cutters
• Spark plug socket
• Utility knife
• Flashlight or headlamp
• Marine sealant and waterproof tape
• Rags and a small bucket
How to Store Your Spare Parts
Good storage keeps parts ready to use.
• Use a sealed, waterproof box or dry bag.
• Label parts by system, such as engine, fuel and electrical.
• Keep a list of part numbers for your engine.
• Check the kit at the start of every season.
Common Mistakes with Boat Spare Parts
• Buying generic parts. Always match parts to your engine model.
• Never checking the kit. Rubber parts like impellers age over time.
• Mixing metals. Use marine-grade stainless or bronze in saltwater.
• Forgetting tools. A spare part is useless without the right tool.
