I have a 1999 Voyager 248, and I think its about time I replace the helm seat cushions. I ordered the Wise WD562 cushions, and we'll see how they fit. They look to me to be a direct replacement, and I believe Wise is the origial cushion supplier to Grady at that time, so...I'm keeping my fingers crossed. Now all I need to do is replace the stern cushion above the batteries and the bolster above it. I thing Wise sells the bolster, but I think I'm going to have to go directly to Grady for the stern seat cushion.
