Sierra 18-4204 Marine Plastic Bushing for Volvo Penta Stern Drive

The Sierra 18-4204 is a replacement plastic bushing engineered for Volvo Penta inboard/outboard stern drive units. Manufactured by Sierra (Sea Star Solutions), this bushing is a direct aftermarket replacement for Volvo Penta OEM part numbers 826341-0 and 876278-3, as well as GLM 23090.

Constructed from high-performance thermoplastic materials, this bushing is designed to perform reliably in demanding marine environments. The composite construction combines thermoplastic alloys and a reinforcing fiber matrix for excellent strength and durability. Unlike metal bushings, plastic bushings are inherently self-lubricating and are unaffected by water, salt, and other marine substances, reducing maintenance requirements.

Key Features:

• Direct OEM replacement for Volvo Penta stern drive applications
• Self-lubricating construction — no greasing required
• Resistant to water, salt, and corrosive marine conditions
• High-performance thermoplastic construction for strength and low friction
• Meets or exceeds OEM specifications
• Sold individually (one bushing per package)
