Welcome to the new Wizard Outboard Forum.
I can't find the post, but it seems I remember someone looking for the engine shroud to go around their WG-4. I spotted this mis-marked one on Ebay: http://www.ebay.com/itm/271530248876?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Same item relisted: http://www.ebay.com/itm/Vintage-1951-Wizard-MG-4-Out-Board-Engine-Cowl/281374757145?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D23769%26meid%3D8019387328576746412%26pid%3D100011%26prg%3D10163%26rk%3D1%26rkt%3D10%26sd%3D271530248876
