Overview

The Attwood Marine 818440 is an aluminum seat mount for LakeSport 238 pedestal systems that use a 2-3/8 inch post. It adds friction control to keep seat movement from feeling too loose, carries a 3 degree tilt, and sits at a 5/8 inch installed height, so it works well when you want a low seat position without changing the pedestal setup much.

This mount makes sense at the helm or on a fishing seat where a little resistance in the swivel feels better than a seat that turns too freely. On a runabout, skiff, or utility boat, that can make the seat feel more settled when the hull rocks at the dock or shifts through turns.

Key features

• Fits LakeSport 238 pedestal systems with a 2-3/8 inch post diameter
• Friction control lets you set seat swivel resistance for a more controlled feel underway and at rest
• 3 degree tilt changes the seat angle slightly, which helps the seating position feel more natural
• 5/8 inch installed height keeps the mount low on top of the pedestal
• Aluminum construction suits marine seating installations where weight and corrosion matter
• Part of the LakeSport 238 seating range, which is built to exceed ABYC standards

Compatibility and fit

This mount is for the 2-3/8 inch LakeSport pedestal size, so checking post diameter before ordering matters. Seat hardware from different pedestal families can look similar in photos while using different diameters and different locking geometry.

The low 5/8 inch installed height is useful when you are replacing only the top mount and want to stay close to the boat's current seat height. That helps on boats where sightline at the helm and leg room under the wheel are already where they need to be.

Use on board

Friction control is useful anywhere the seat needs to turn but should not swing loose every time someone shifts weight or the boat rolls. That suits helm seats, casting seats, and other fixed-height pedestal layouts where controlled movement matters more than added slide travel.

This is a good match for boat owners replacing a worn LakeSport top mount or keeping a simple pedestal seat setup that stays low and easy to live with. It works best when the rest of the seating system already matches the same 2-3/8 inch standard.
