Why Carry Spare Parts on Your Boat?
Chris was a Boy Scout and a Sea Scout so we believe in being prepared. Here is a basic idea of spare parts we recommend you carry aboard just in case. By no means is this a complete list, but it’s certainly a good start.
Even if you are uncomfortable doing the repair yourself, keep these items aboard. Why? If you already have the part onboard, you won’t have to wait for it to be delivered to you somewhere along your journey–and you can always hire a local tech to do the job for you if you have the parts.

Filters and Fluids Every Boat Should Carry
It’s important to know when your next oil change is required. All engines require different oil weights for different climates. Your generator may use a different oil brand, type or weight than your propulsion engine. The transmission may require engine oil or ATF (automatic transmission fluid). Information such as this is good to know before you go.
Carry enough spare oil to do a complete oil change plus a gallon or so of extra oil to top off the engine when needed. Purchasing the oil in 1-gallon jugs instead of the 5-gallon bucket makes it easier to handle and store in small engine room spaces.
Don’t forget the oil filters. Fuel filters for each propulsion engine and generator should also be on your list. Sometimes things go splash so extra deck plate keys and tools to open fuel, water and waste covers are appreciated.

Must-Have Marine Tools for Onboard Repairs
Get the right tool for the right job. Bargain tools are not good enough for your engines. Use plastic tool boxes less than 24 inches in size. Here’s a time when BIGGER is not better. You never have enough tools until you try to pick up your tool box! Try splitting things up into several boxes and take it easy on your back. Keep the tools in the area you plan to use them.
Electrical Troubleshooting Equipment to Keep On Board
Have parts and instruments available to trouble shoot and repair simple problems that arise. A digital multi meter can read AC and DC power. Make sure this meter has an audible conductivity feature so you can test fuses, circuit breakers and loose connections especially when you cannot see the meter because of your contorted position in the engine room.

General Spare Parts That Prevent Major Breakdowns
These next items may seem arbitrary but the little things are often what can make a difference in a successful day on the water. Entering an engine room is safer with ear protection. A rubber impeller kit may help in an overheating situation. Be sure to use the special impeller puller tool. And if your alternator belt shreds, a spare belt can save the day. The right coolant (also known as antifreeze) will keep your engines purring.
A special filler jug will help you add distilled water to flooded lead acid batteries. Spare pumps for bilge, shower and fresh water systems will be easy to change out in a jiffy. An extra float switch for the bilge pump can save the day. It is a good habit to have flashlights located at all exits and bedsides with batteries ready to change quickly. That dark below deck space is now bright and easy to see with a compact mirror to peek around corners. A box full of varied hose clamps makes quick repairs on a loose hose. And assorted size wood plugs should be accessible for through-hull emergencies.
OEM vs Aftermarket Marine Parts
This list is meant to get you started thinking about parts specific to your boat. Remember that if your equipment is under warranty, you must use OEM (original equipment manufacturer) parts and supplies to maintain that warranty. Ask yourself: Where will I store it and what am I willing to compromise? Spare parts can keep your pleasure boating on course.
