Attwood Marine Motor Well Boot, 4 in Diameter Opening, Split Side, 2pk

Overview

The Attwood Marine 12820-5 is a motor well boot for a 4-inch diameter opening that gives cables, wiring, or fuel lines a covered pass-through at the motor well. The split side lets it wrap around existing rigging, so it can be installed without disconnecting engine controls.

This boot uses black rubber with UV resistance and a polypropylene attachment gasket ring. It works well in exposed transom and splashwell areas where sun, spray, and constant movement can wear out an open rigging pass-through.

Key features

• Fits a 4-inch diameter motor well opening
• Split-side construction allows retrofit installation around existing controls
• Routes control cables, wires, or fuel lines through a covered opening
• Black rubber body with UV resistance for exposed rigging areas
• Polypropylene attachment gasket ring helps keep the boot secured in place
• Pack includes two boots and ties for fastening

Compatibility and fit

This boot suits outboard-powered boats that need a covered pass-through in the motor well or splashwell. It is a good match for control cable bundles, wiring harnesses, or fuel line runs where the opening size is 4 inches.

Before ordering, check the opening diameter at the mounting point rather than the rigging bundle itself. The fit is based on the hole size in the boat, not only on the number of cables or lines passing through it.

Installation and use

The split side makes this a practical replacement part when older motor well boots have cracked or hardened with age. It can be fitted around existing rigging during service work without pulling cables apart, which helps keep a repower, re-rig, or cleanup job moving.

On board, this boot is a sensible choice for skiffs, center consoles, aluminum fishing boats, and other outboard setups where the transom rigging needs to stay contained at the pass-through. It is especially useful when the goal is to tidy the motor well area without changing the rest of the rigging layout.
