The problem with the Volvo Penta instruments screens
In many cases with the screen problems I see in the Marina sailors buy a new instument at + 600,- €
The Volvo Penta instruments are equipped with thin (1mm) double plexiglass, with a few millimeters of space in between. After only a few years, the first layer becomes brittle, yellow, difficult to read andand possible water between the two layers. You can remove the front layer with a sharp and hot knife.
The front layer has been removed on the right-hand picture.
