Your motor's inlet grilles are rectangular and the round flusher just won't seat. Water splashes past the edges, the cooling passages stay salty, and you're gambling with a $3,000+ engine every time you skip a flush. This rectangular cup measures 140 × 90 mm with extra-deep arms that grip the outboard leg properly so the hose pressure actually pushes water through where it needs to go. Clip it on, run the hose, check the joint, start the motor out of gear. Done before you've finished your coffee
