Review exact listingIdentify Attwood 238 Pedestal Kits, LakeSport & Extension Posts
Replacing a pedestal or seat mount on an older fishing boat, pontoon or other marine seating installation? Attwood's 2⅜-inch 238 Series and LakeSport components share a nominal post diameter, but the specific model number determines whether you are looking at a complete kit, an extension post or an adjustable assembly. Use the original number and mounting configuration to identify the replacement.

The 23809-7 and 23815-7 are kits that include the post, swivel seat mount and 9-inch round base. The 238613-1 and 238615-3 are separate standard extension posts. The adjustable 2385405 and 2385400 are LakeSport bell-style pedestal assemblies with seat mounts. A post by itself should not be mistaken for a complete pedestal kit.
Check the seating classification: AO designates an operator-position component, AN a non-operator Type A component, and B a lower-speed non-helm application. The AN-rated 2385400 and 238613L1 are not direct operator-position replacements for AO-rated parts. Complete seat-assembly suitability must also be established.
Checks before buying replacement pedestal hardware
- Read the full model number. The LakeSport-only 238613L1 has different intended usage from the standard 238613-1 despite both having a 13-inch installed height.
- Check the assembly components. Complete kits include a base and mount. Standalone extension posts need appropriate matching hardware.
- Compare installed height. The standard 238613-1 and 238615-3 heights are measured from deck to the top of the seat mount; the kit numbers identify post lengths.
- Identify the operator position. Do not replace an AO-rated operator-seat component with AN or B hardware on the assumption that the post diameter makes it interchangeable.
- Confirm mounting details. The 23809-7 and 23815-7 kit bases are 9 inches round with a 3-inch deck-hole requirement. Verify the actual fastener pattern and space beneath the deck before modifying the installation.
- Match seat mounts as well as bases. LakeSport has specific seat-mount requirements. A similarly sized post does not prove compatibility with a different mount or another manufacturer's hardware.
- Inspect the existing hardware. Check for corrosion, bent components and damaged locking connections; review the condition and included components in each product listing.
