If you’re a boat owner, you may have noticed some strange holes in the back of your boat. What are they for? What do they mean? In this blog post, we will answer those questions and more.
We’ll discuss what each hole is used for and what it means when one is blocked or missing. So what are the 3 holes on back of my boat? Let’s find out.
What the Three Holes on the Back of a Boat Are For
So you’ve just bought a new boat, or maybe you’re thinking about buying one. You take it out for a spin on the lake and notice there are three holes on the back of the boat. Now, you’re probably wondering what those holes are for.
The truth is, there are a few different things that those holes could be used for. Let’s take a look at a few of the most popular theories.
The first theory is that the holes are used for drainage. This is probably the most popular theory, and it makes sense. The holes are located in the back of the boat, which is where water would typically build up.
By drilling holes in the back of the boat, water can easily drain out, preventing the boat from taking on too much water and sinking.
The second theory is that the holes are used to attach a motor. This one is also fairly popular, especially among people who own smaller boats.
The holes provide a place to attach a motor, which can then be used to help the boat move through the water.
The third theory is that the holes are used for storage. This one is less popular, but it does make sense. The holes can be used to store things like ropes or life jackets.
Putting these items in the holes will be out of the way and won’t take up valuable space inside the boat.
What Each Hole is Used For
The three holes on the back of your boat have different purposes based on their location and what kind of boat you have.
The first hole is located at the top of the transom, nearest the outboard motor. This is typically where a flag is flown on pleasure craft, or a racing number is displayed on a sailboat.
The second hole is located in the center of the transom and is used as a drain plug. When removed, it allows water that has made its way into the boat to drain out.
The third and final hole is located at the bottom of the transom. On powerboats, this is where the rudder post extends through the hull and is held in place with a nut and washer on the inside.
Sailboats do not have a rudder post extending through this hole. Instead, it is used as a drain plug like the one in the center of the transom.
How to Use the Holes to Your Advantage While Boating
The three holes on the back of your boat each serve a specific purpose. While you may not use all of them every time, you go boating, understanding what they are for can help you take advantage of them when the situation arises.
The first hole is called the drain plug. This is where water can exit the boat if it gets inside. The second hole is called the fill plug.
This is where you can add water to the boat if it needs it. The third hole is called the vent plug. This is where air can enter the boat if it needs it.
Knowing what these holes are for can help you in a few different situations. For example, if your boat starts to take on water, you can open the drain plug to let the water out.
If your boat is low on water, you can add more fill plugs. And if your boat is having trouble staying afloat, you can open the vent plug to let air in and help it float better.
So next time you’re out on the water, take a look at the three holes on the back of your boat and remember what they’re there for. You never know when they might come in handy.
The Benefits of Using All Three Holes While Boating
Your boat has three holes in the back, also known as scuppers. These are designed to allow water on your deck to drain overboard and not pool around your feet while you’re boating.
If water does happen to build upon your deck, it will flow through these scupper holes and out of the boat.
The three scupper holes on your boat have different functions, and it’s important to know what each one is used for. The first and largest hole in the main drain.
This hole will allow the most water to flow out of your boat quickly. The second hole is called the emergency drain, and it’s slightly smaller than the main drain.
This hole is used in case of emergencies when you need to get rid of water on your deck quickly. The third and final hole is called the live well drain.
This hole is used to drain water from your live well or bait tank so that it doesn’t overflow onto your deck.
Using all three of these holes while boating will ensure that your deck stays dry and free of any water build-up.
Now that you know what the three holes on the back of your boat are used for, make sure to put them to good use the next time you’re out on the water.
Examples of When You Would Want to Use Each Hole
- The first hole is the stern light. This is used when it is dark outside and you want people to be able to see your boat from behind.
- The second hole is the vent hole. This is used to let air in and out of the boat so that it doesn’t get too hot or too cold inside.
- The third hole is the drain hole. This is used to let water out of the boat so that it doesn’t get too full.
So there you have it. The three holes on the back of your boat and what they mean. Now you’ll be able to tell people what they’re for next time you’re out on the water.
Why Are There Three of Them?
The three holes on the back of your boat have different purposes. The middle hole is for towing and is also used as a drain plug. The two side holes are vents for the engine compartment.
The middle hole is sometimes used as a mounting point for an outboard motor bracket. However, this isn’t the best way to mount an outboard motor. The side holes are for mounting fishing rod holders.
One other thing to note about the three holes on the back of your boat is that they should be covered when not in use. This will help keep water and debris out of the holes. You can cover the holes with plugs or caps.
Where are they located?
The three holes are located on the back of your boat, near the stern. There are two small ones and one large one. The large one is in the middle and is usually covered by a cap. The two small ones are on either side of the large one, usually uncovered.
How do I clean them?
If you have never cleaned your boat’s hull before, start washing it with fresh water and a soft brush. You can use a mild soap if needed. Be sure to rinse the hull thoroughly afterward.
Next, you will need to sand the hull using medium-grit sandpaper. Again, work in small sections, and be sure to sand evenly.
Finally, you will need to apply a primer and paint to the hull. Once the paint is dry, you can apply a clear coat to protect it from UV rays and water damage.
So, what are the three holes on the back of your boat? Well, they have a few different purposes. The first two are usually for drainage, while the third is typically used as a fill point for your boat’s bilge pump.
However, it’s always best to consult your owner’s manual to be sure. Nevertheless, we hope this article was helpful and that you now understand what those holes are for.
