    25hp mariner by yamaha

    I just purchased this motor and was told that it is a 1983. It is a tiller now, and I use it as a tiller, but looks like it probably was a remote steer. Is this normal? Did they come with both options? I took it out for the first time and it seems to run great except for a couple issues...
