🔧 Product Description

Genuine Suzuki / Johnson Water Return Union - Part Numbers: 51115-90J00 / 5033841

A genuine Suzuki-manufactured water-return union used in the engine-holder and exhaust-adapter cooling system of selected Suzuki and Suzuki-built Johnson four-stroke outboards.

Suzuki part number 51115-90J00 directly cross-references Johnson / Evinrude part number 5033841. The fitting connects the applicable cooling-water return passage and must seal correctly against the matching O-ring and engine-holder components.
