Just got my 1977 Tiara 2000 with Mercruiser 898 alpha 1 from the shop and tested it out on a local lake. Everything seemed to work fine, but I had no steering whatsoever. It was locked, couldn't turn the wheel or the outdrive by hand. Steering was fine before I took into the shop which makes me think they just forgot to connect everything, whatever that may be I don't know. I wish I knew more about steering, but I had no chance of fixing it myself lol. Anything stand out that might be obvious and is something like this common?
