I took my 1987 Sea Ray Seville 17 out yesterday, got it off the trailer and found that I couldn't turn the steering wheel. This is the first time in 2 years I was able to get it in the water. I paid $800 to get a tune up and would like to fix the problem on my own. Does anyone have any idea of what could be wrong or any idea where I can buy a parts/owner's manual for the boat? Thank you to anyone that can point me in the right direction.
