Recently purchased a Z-54 and have some questions if anyone can help. I thought I was getting the original manual with the boat but no such luck. 1. Anyone know where I can get an original manual describing systems and their operation? 2. I was told the boat holds 1400 gallons of fuel. Does anyone know the capacity of the cockpit tank and the engine room saddle tanks? 3. Did these boats come original with engine waste heat plumbed to domestic hot water? 4. There are P&S water tank fills but I don't see a valve manifold anywhere to draw from one or the other tank. Do they have a built in crossover so they automatically draw and equalize? Thanks in advance for any help.
