Mercury is proud of their products, just look at the prices! The 850/6 combo is right at $100,000US if I remember correctly. That would put the new 700/Ace drive right around $85,000.
I can get a 705ci/1000hp motor for $35,000(
www.marineassault.net) and a bulletproof ASD8 surface drive for $25,000.
There are lots of engine and drive builders here in the States. I will support those guys because they are doing their best to compete with Mercury the Giant.
