Andrew told me how to install $135 water tank gauge and sensors on the R-25. However, after cutting the hole I thought why install an expensive gauge system when you can see how much water is in the tank? Remove port side teak trim strip, cut hole larger to fit new teak trim cover plate, glue wood measure onto tank, install access door stainless steel spring pressure latch. To check the of water in the tank, pop the teak trim plate off, and use flashlight to see how many inches of water are in the tank... (See Little Toot's photos)
