    If it is the case that the lens is very scratched and that is the cause of your issue you could try just replacing that:

    VOLVO PENTA LENS 827766


    Or just removing it and using 1000/2000 grit wet/dry paper polish it. I saw a tube of someone who did this and it looked like new after polishing.
