missing engine control cover

[Sailorman Ed]

OK, another fun thing when you buy an old boat and the PO is out of the picture. So my "new" cat with twin 2 cyl Yanmars has single lever controls (one for each engine) but the cover over the middle is missing (was covered with 3 layers of plastic bags, now down to 2 layers) and I hope to finally get it into the water and bring it home. The PO does not know what happened to the cover nor does he know what brand it is. Yanmar engines and looks like Teleflex cables. Did not notice any marking on it. There cannot be too many mfg who make these. Suggestions on how I go about getting a cover?
