I am looking into buying a 1977 mercury 115hp with power trim. The motor runs great comes with extra lower unit extra trim pump and motor stand. The only reason I haven't already snatched this up for the great price he has listed on it is because he does not have the remote controls for it. He also says that the internal wiring harness could be replaced because it is a little frayed. This motor takes the old 7 pin style harness. For the life of me I cant find the controls for it. If any one has advise on what I should be looking for please let me know. Also if any one knows if there is any way to adapt this motor to the newer style 8 pin harness and controls please let me know. This is a great deal and all advise is appreciated. I need all the help I can get asap so I do not miss this deal. Thanks everyone.
