I have the same problem with the foil on the panel for my 4JH4 engine. There is a part number for just the plate and the foil, but Yanmar has discontinued that item and the only option was a complete new panel. The local (JAX, FL) Yanmar dealer did call the area distributor (Mastry) and found out that a shop in Ft. Lauderdale, Complete Yach
t, is making up the foil for one of the panels. Unfortunately, I need the "C" panel with oil
pressure and water
temperature guages and he is just making the foil for the "B" panel, which looks like the one in your picture.
They are looking into making the foil for the "C" panel, but I have no commitment. I also don't know what they want for the "B" panel foil, but it should be worthwhile to give them a call. They said they would have those foils available in about 2 weeks.
