I am very interested in the 200hp engines. I need to know the following. Are the Shangchai engines similar to the Cummins engines? I need full details of Physical size, fuel consumption, and power curves, RPM for engine and various fuel consumption at different RPM. Weight of engines. I want this for the 200hp Shangchai and the 200hp Cummins engines. Also how long would it take to get some sample engines made? What warranty, spare parts etc. Please also send price to include cables, alternator and 2:1 reduction Gearboxes. If you can get these and some pictures or a web site I can see these as soon as possible please. In the price of Cummins 200hp at $16250 USD does this include gearbox and cabling and alternator? if not what total price.
