Mercruiser Engine? Where is the fuel tank located? Is the Tank Aluminum or Plastic? I read one place it was Aluminum. I hope it is, less chance to crack. Also how do I check the Stringers and the transom on this boat? Stringers wood or fiberglass? How thick is the hull? What is it constructed of? Solid Fiberglass? Also I'm replacing the 350 Mercruiser Engine. What is the best repair manual for this boat and engine? I already took the old 350 out, it has a cracked block... Thank You, Chris
