HOW TO INSTALL A SHOCKABSORBING SEAT PEDESTAL

The versatile Shoxs helm-seat pedestal system from Allsalt Maritime softens hard landings.

Some say that the worst day of boating is better than the best day at the office. But that’s not true. I’ve endured too many wind-swept, slambang days on the water when I pined for terra firma. Such a scenario played out as we exited Miami’s Government Cut for a sea trial of the new Allsalt Shoxs helm-seat pedestal system.

Menacing 4- to 5-footers rose up and rolled in as

Capt. Jordan Tilton powered through the steep seas aboard a 27-foot centerconsole Safe Boat. Seated in the port helm seat, I tensed and braced in anticipation of impact as we crested the face of each wave, but the pedestal softened every landing. I was riding on a cushion of air that gives this system its shock-absorbing qualities.

Installing a Shoxs pedestal is a relatively easy DIY project, particularly if you already have a conventional seat pedestal. You can install the new pedestal on the footprint of the old one. Allsalt offers a wide range of shockabsorbing systems for commercial and military applications, but this system is designed for recreational boating and built from marine-grade aluminum with a hard-anodized silver finish. It comes in two versions, each with or without an incremental height-adjustment feature. Both include a standard square seat mounting plate with a 5¼-inch bolt mounting pattern, which is fairly common for most marine seats.

For this project, we decided to install the

Shoxs X8 with the heightadjustment feature as a retrofit to the traditional pedestal on a Parker 2320 pilothouse boat. Before getting started, we removed the existing 27-inch-tall pedestal from the boat, unbolted the bucket seat (saving the hardware to reinstall the seat on the

X8), and checked under the deck to ensure that no electrical wires, hoses or other components would be damaged when drilling holes.

MOUNTING STYLE

The mounting flange/base comes installed in the lowest position available on the pedestal for surfacemounting. We chose this position to give us the height for this project. However, you can position the flange/base higher on the pedestal should the X8 need to recess into a deck or box for a lower seat position. This requires cutting a 63/4-inch-diameter hole in the mounting surface, unbolting the flange from the bottom side, sliding it up the pedestal, and retorquing it to factory specs.

MOUNTING HOLES

Center the supplied mounting template over the footprint of the old base and mark the position for drilling the six new mounting holes for the 10-inch-wide flange/base. Make sure the template is oriented properly, with one mounting hole positioned at the front and the other at the back of the flange, parallel with the centerline of the boat. Use a power drill and a sharp 3/8-inch bit to drill each hole. A right-angle drill guide ensures that each hole is cut perpendicular to the deck.

INSTALL BASE

Bed the mounting holes with a marine sealant or adhesive, and place the pedestal and flange in a position that allows easy access to the side Schrader valve’s air-fill port. Use 3/8-inch 16- or 24-thread high-strength stainless-steel Allen bolts (not supplied) of sufficient length to span the thickness of the flange, deck and backing plate or fender washers, and allow the nylon locking nuts to engage at least 0.56 inch of the bolt threads. Add threadlocker such as Loctite 243. Tighten each fastener.

INSTALL SEAT

The Shoxs pedestal comes standard with a square adapter plate that pairs with a boat seat with a traditional 51/4-inch hole pattern. Remount your existing helm seat with this plate using a mediumstrength threadlocker. If you have a helm seat that does not fit the standard hole pattern, Shoxs offers additional optional seat-mounting adapters. Allsalt also offers a wide range of helm seats with optional features, such as footrests, fold-down armrests and flip-up bolsters.

ADJUST HEIGHT

The X8 height-adjust model lets you fine-tune the pedestal height from 25.7 to 30.1 inches tall. Use the spring-loaded knob on the side of the pedestal to retract a locking pin and telescope the seat up or down. Pull the knob and adjust to the desired height. The pedestal might not rise on its own, depending on the seat weight, so you might need to pull the seat up while the pin is disengaged. To lock the height in position, release the knob, then bounce in the seat to ensure the pin is locked.
