I need some help. I have a 1980 25ft buc sailboat, without a motor. I have put a mount on the stern for an outboard, and have been given an outboard for it. It is an 8hp Nissan that was originally factory installed on a 1991 F-27. It was connected with remote controls and does not have a twist grip throttle handle on it. It is an electric start, alternator, and remote fuel tank. The problem: I would like to convert this back to a manual twist grip throttle handle, but don't know how to do it, and if it is possible at all. Any help would really be appreciated. Thanks
