We bought our first boat 3 weeks ago. 1983 Sea Ray. Great boat. My buddy pointed out that I've got a little slop in the steering. Upon closer inspection and some research, I see that the stern drive is not tight to the upper swivel shaft. In a Mercruiser manual, it reads "Mercruiser I-Drive Transom assemblies (s/n 5490562 and above) use a square (instead of a splined) connection between the upper swivel shaft and gimbal ring. Can someone give me a hint as to what to do about this slop, if anything? Do I need to immediately stop using the boat and fix it? What does fixing it involve? How much should I expect to pay for the repair? I'm still learning....Thank You Very Much! We've had some awesome times in our 3 weeks owning this boat and looking forward to this weekend!
