Installing A Boat Pedestal: A Step-By-Step Guide

Installing a boat seat on a pedestal is a great way to get a better view of the water and can make boating safer. It's a job that many boat owners choose to do themselves, but it's important to get it right to avoid a leaking deck. Before you start, you'll need to decide on the position of the seat, ensuring it's not too close to the wheel or tiller. You'll also need to check the type of decking under the seat and the structures (if any) under the deck. If you have a fiberglass boat with thin decking, you may need to add a backing plate, which can be made from aluminium. Once you're ready to install, you can mark the mounting holes, drill, and secure the base with bolts, washers, and nuts.

Choosing the right pedestal for your boat

Choosing the right boat seat pedestal is essential for a safe and enjoyable boating experience. Here are some factors to consider when making your selection:

Type of Boat and Activities

The type of boat you own and the activities you plan to do on the water are crucial considerations when choosing a boat seat pedestal. For example, if you have a standard fishing boat, you'll typically find seat swivels that provide access to all sides for optimal fishing. On the other hand, if you have a ski boat, you'll want permanently mounted driver and passenger seats, with removable pedestals for the fishing seats.

Boat Styles and Seating Arrangements

Understanding the different boat styles and their seating arrangements can help you make an informed decision. For instance, bass boats are designed similarly to standard fishing boats but differ in the seating arrangement. They have Class A seats for the driver and passengers during transit and removable pedestals for the fishing seats at the front and rear of the boat.

Adjustable vs Fixed Height

It is recommended to choose an adjustable boat seat pedestal to customise the height according to individual needs. Whether you're looking for more lumbar support or a specific seat height, adjustability allows you to create the perfect fit for maximum comfort.

Shock Absorption and Stability

A high-quality seat pedestal should offer good shock absorption to keep you safe and comfortable, especially in rough waters. Look for pedestals with advanced suspension systems that reduce the shock transmitted to your legs and back. Additionally, ensure that the pedestal is stable and doesn't wobble or rattle, even in challenging water conditions.

Material and Durability

The material of the boat seat pedestal plays a vital role in its durability and performance. Aluminium is a popular choice due to its corrosion resistance and lightweight properties. Stainless steel is another excellent option for marine environments as it offers exceptional strength and corrosion resistance, making it ideal for saltwater exposure.

Installation and Compatibility

Ease of installation is an important consideration. Look for pedestals with pre-drilled holes in the base and mount for straightforward assembly and attachment to the boat floor and seat. Additionally, ensure that the pedestal is compatible with the boat seat you intend to use. Check the position of the holes and the type of connection between the mounting bracket of the pedestal and the base of the seat.

Brand Reputation

Opting for a reliable brand can give you added peace of mind regarding the quality and performance of the boat seat pedestal. Attwood, Wise, and Leader Accessories are well-known for their high-quality and durable products.

Preparing the surface and drilling holes

Step 1: Clean the Surface

Before installing your boat pedestal, it's essential to prepare the floor of your vessel thoroughly. Start by cleaning the surface with a brush and a mild detergent to remove any dirt, grime, or old adhesive. This step ensures that your pedestal has a stable and non-slip surface to sit on.

Step 2: Determine the Type of Decking and Underlying Structures

It's important to determine the type and solidity of the decking under the intended seat location. Some boats have thin fiberglass decking, which may or may not be cored. If possible, try to inspect underneath the deck to identify any supporting structures, such as beams or ridges. This information will help you choose the most secure fastening method.

Step 3: Decide on the Fastening Method

Consider the anchoring method you will use to attach the pedestal to the floor. Common options include bolts and screws. Bolts are often preferred as they can provide more holding power than screws, especially when paired with backing washers and nuts. Choose an anchoring method that suits your boat's design and the weight capacity of the pedestal.

Step 4: Position the Pedestal

Decide on the position of the seat base. Ensure it is not too far back or too close to the wheel or tiller. Consider your ease of access to the steering while sitting and, if applicable, while standing in front of the seat. Mark the position of the pedestal on the floor.

Step 5: Drill the Holes

With the pedestal positioned, it's time to drill the holes. Start by drilling a single hole through one of the base's mounting holes. Insert a bolt or screw without caulking it. Then, on the opposite side of the base, drill a second hole and repeat the process. With these two fasteners in place, you can secure the pedestal and drill the remaining holes without worrying about the base shifting out of position.

Step 6: Clean and Seal the Holes

After drilling all the holes, remove the fasteners and the pedestal. Clean the area by removing any shavings and fiberglass dust created during the drilling process. Then, apply a marine-grade caulk or adhesive/sealant to each screw hole and, if possible, into the holes to seal any coring. This step helps prevent leaks and ensures a secure installation.

Step 7: Install the Pedestal

Finally, reinstall the seat pedestal by lining up the holes with the caulked holes. Push one fastener through the base and use it to align the base over the holes. Then, drive in all the fasteners securely.

Remember to follow the manufacturer's instructions for any specific requirements or adjustments, and don't hesitate to seek professional help if needed.

Using the correct screws or bolts

Using the correct type, size, and material of screws or bolts is crucial for the safety and stability of your boat seat pedestal. Here are some detailed instructions and considerations to help you choose and install them properly:

Understanding Your Boat's Materials and the Seat Pedestal:

Before selecting the screws or bolts, it is essential to consider the materials of your boat's deck and the seat pedestal. If you have a wooden deck, choose screws or bolts that won't corrode and are long enough to anchor securely into the wood without protruding through the other side. For metal or fiberglass decks, opt for fasteners that can handle these materials without causing damage. Stainless steel or brass fasteners are ideal for their strength and corrosion resistance.

Considering the Seat Pedestal Design and Size:

The material and design of the seat pedestal will also influence your choice of fasteners. Make sure the screws or bolts are compatible with the pedestal's material. Additionally, the height and diameter of the pedestal will determine the size of the fasteners. Larger pedestals will require heftier screws or bolts.

Choosing the Right Type of Screw or Bolt:

The type of screw or bolt you choose depends on the material of your deck. For wooden decks, wood screws are the best option. If you have a metal or fiberglass deck, machine screws or bolts may be more suitable. Self-tapping screws can also be used but ensure they are made from durable materials like stainless steel.

Picking the Correct Size:

Consider both the length and gauge of the screws or bolts. The length should be sufficient to secure the pedestal without protruding through the deck. The gauge should be appropriate for the material—too large can cause splitting, and too small may not hold securely.

Prioritizing Quality:

Always opt for high-quality, corrosion-resistant, and durable fasteners. While it may be tempting to save money on cheaper options, investing in quality will ensure your boat seat remains securely fastened, even in harsh marine conditions. Regular maintenance and inspections of the fasteners are also crucial to ensure longevity and safety.

Test Fitting and Pre-drilling:

Before fully installing the screws or bolts, perform a test fit to save time and prevent potential damage. Additionally, pre-drilling small holes before screwing or bolting can help prevent splitting or damage to the pedestal.

Securing the Fasteners:

When tightening the screws or bolts, be careful not to over-tighten them, as this can damage the fasteners and the pedestal. Apply just enough force to keep them secure.

Seeking Professional Help:

If the installation process seems too complex or you have any doubts, don't hesitate to seek professional help. It's better to be safe than sorry when it comes to the safety and stability of your boat seat pedestal.
