Abstract
A lash adjustment device is for a valve train in a marine engine. The lash adjustment device comprises an external hollow body and a ball shaft that is telescopically movable in the hollow body. The ball shaft has a through-bore for receiving oil and having an annular lower end surface and an upper end surface. Oil flow into the hollow body pushes on the lower end surface and forces the ball shaft to telescope outwardly with respect to the hollow body. An absence of oil flow in the hollow body allows the ball shaft to telescope inwardly with respect to the hollow body until the annular lower end surface engages with an internal stop surface formed in the hollow body.
