PartX Recommends

Lower-unit sealing work is labor-intensive and a leak or water intrusion can lead to expensive gearcase damage. The Japanese OEM kit’s controlled materials, packaging, and proven fitment make it the safest overall choice while still offering strong value when you factor in the consequences of a redo.
