What You'll Learn
Drilling holes and securing the base
Before drilling any holes, it's essential to determine the type and solidity of the decking under the seat. Check if there are any supporting structures, such as beams or ridges, under the deck. This step is crucial because it helps identify if there's a need for additional support or if there are any potential interferences during installation. If possible, try to peek under the deck to assess the supporting structures.
The next step is to decide on the position of the seat base. Ensure it is not too far back or too close to the wheel or tiller. Mark the position for drilling the mounting holes. It is recommended to use a power drill and a sharp 3/8-inch bit to drill each hole. Drill straight through the mounting holes to ensure proper alignment.
After drilling the holes, it's important to bed the mounting holes with a marine sealant or adhesive. This step helps create a watertight seal and adds stability to the installation. Place the pedestal and flange in the desired position, ensuring easy access to the side Schrader valve's air-fill port.
When securing the base, it's recommended to use high-strength stainless-steel Allen bolts or screws. Choose bolts or screws that are long enough to span the thickness of the flange, deck, and backing plate or fender washers. Drive the bolts or screws into the mounting holes, ensuring they are tight and secure.
If using screws, be aware that they can weaken the decking over time as they work loose due to the stress and pounding of the boat. To mitigate this, consider using a backing plate to provide additional support and distribute the stress more evenly. You can also install an inspection port to access the underside of the screws and tighten them with a wrench if needed.
By following these steps and taking the necessary precautions, you can securely drill the holes and fasten the base of the boat seat pedestal to your fiberglass boat.

Using screws or bolts
- Inspect the Deck: Before installing the seat pedestal, it is important to inspect the deck and underlying structure. If possible, look underneath the deck to identify any supporting structures. This will help determine the best method for securing the pedestal.
- Choose the Right Fasteners: Select high-quality stainless-steel screws or bolts that are specifically designed for marine use. Stainless-steel Allen bolts and nylon locking nuts are a common choice for this type of application.
- Determine the Mounting Location: Decide on the exact location for the seat pedestal, ensuring it is positioned correctly in relation to the steering wheel or tiller. Make sure there is enough clearance for drilling and that the pedestal will not interfere with any other components.
- Drill Pilot Holes: Mark the mounting location and drill pilot holes to check for any underlying structures. Drill carefully to avoid damaging any critical components. It is important to note that some fibreglass boats have thin decking, so using the correct drill bit size is crucial.
- Apply Sealant: Before inserting screws or bolts, apply a marine-grade sealant or adhesive to the holes. This will help prevent water intrusion and protect the decking from rotting. Silicone or epoxy can be used for this purpose.
- Install the Pedestal: Place the pedestal base over the holes and insert the screws or bolts. Use a wrench to tighten any nuts and ensure a secure fit. If using screws, ensure they are driven straight and aligned correctly to avoid an uneven stress load.
- Final Checks: Once the pedestal is securely mounted, perform a final inspection. Check that the screws or bolts are tight and that the sealant has been applied properly. Test the stability of the pedestal by applying some weight but avoid sitting fully until the sealant has cured.
It is important to note that using bolts may be preferable to screws as they can be secured with backing washers and nuts, providing a more secure installation. Additionally, if the decking is thin, consider using a backing plate for added support.

Adding a backing plate
To install the backing plate, you can pre-mount the pedestal base to the plate using through-bolts. Then, screw the plate down to the deck using wood screws. It is recommended to use #12 or larger diameter screws and ensure that you use a sufficient number of screws to secure the plate firmly.
If you cannot access the underside of the deck, you may need to consider an alternative method. One option is to simply screw the pedestal base directly to the deck. However, this may not provide the same level of rigidity and support as using a backing plate.
Another option is to create an access hole in the deck to install the backing plate. This can be done by drilling a hole in the deck and using a wrench to tighten the washers and nuts from below. This method ensures that the backing plate is securely attached to the deck, providing a strong and stable base for the boat seat pedestal.
It is important to determine the type and solidity of the decking under the seat before beginning the installation. Some fiberglass boats have thin decking, so it is crucial to check for any supporting structures under the deck, such as beams or ridges. This will help you choose the most appropriate method for mounting the boat seat pedestal and ensure that it is securely installed.

Positioning the seat
Firstly, determine the desired location for the seat. Consider the available space and ensure that the seat will not be positioned too far back or too close to the wheel or tiller. It is important to maintain a comfortable and functional distance from the boat's controls. Imagine yourself seated in the position and visualize your ease of access to the necessary controls and overall comfort.
Secondly, inspect the decking under the desired seat location. If possible, access the area underneath the deck to check for supporting structures such as beams or ridges. This step is crucial to assess the strength of the area and determine if additional reinforcement is needed. Some boats may have thin decking, which can be a factor in deciding the type of fasteners to use.
When positioning the seat, consider the footprint of the previous seat, if applicable. You can install the new pedestal on the same footprint, ensuring a proper fit and avoiding potential structural issues. This approach can save time and effort in drilling new holes and sealing them.
Additionally, be mindful of the height of the seat. You can adjust the height of the mounting flange or base on the pedestal to achieve the desired seat height. A lower seat position may require cutting a larger hole in the mounting surface and adjusting the flange position accordingly.
Finally, consider the type of fasteners you will use. Screws and bolts are commonly used, but the decision depends on the specific conditions and requirements of your boat. For example, bolts may be preferred for their ability to accommodate substantial backing washers and nuts, providing additional support. However, screws can also be effective, especially with plywood decks, as they offer better retention than fiberglass.

Frequently asked questions
First, determine the type and solidity of the decking under the seat and the structures (if any) under the deck. If possible, check under the deck to determine supporting structures such as beams or ridges. Then, with the base and pedestal lined up, drill a single hole through one of the base's mounting holes and run a bolt or screw into the hole. Drill a second hole on the opposite side of the base and drive in another bolt or screw. With the two bolts or screws securing the base, drill the remaining holes and add the rest of the bolts or screws.
Screws can weaken the decking over time and work loose, so bolts are often preferable. If you can access the underside of the deck, you can add a backing plate for additional security. If you can't access the underside, you can install an inspection port to see what you're working with.
Use bolts or screws that are the right size and type for the purpose. For example, if you are drilling into plywood, you will need different tools than if you are drilling into fiberglass.
Before you start, decide where to position the seat so it isn't too far back or too close to the wheel or tiller. Also, be sure you know where your fuel tank is before you start drilling.
