Your configuration will require your network's routing to present the SSH packets from your source host at 10.1.6.18 to the  ASA's management interface,

It seems odd to have the management VLAN's Layer 3 set up as a /16 (255.255.0.0). Is that your intention? If so, you will need to have that consistently set on the VLAN's gateway. Otherwise ARP will not resolve the MAC of your Management0/0 interface.
