I have a 1984 OMC 3.0 with Selectrim. I am trying to find the housing that the trim motor bolts to. The book refers to it as a Trunnion housing. The number stamp on it is 909568. I have looked all over the net but have not been able to find this part except for 1 complete unit on eBay. I know the part is probably going to be hard to find but the housing is broken. Thanks in advance.
