In the description of the remote, there is a mention of adapters for the cables. Since Uflex cables are a direct replacement for Merc cables there shouldn't be a problem. Also they say:
for all outboard engines
Made of nylon fiberglass with anodized aluminum levers
Left or right side mount installation
For use with Teleflex engine control cables: CC205 with K23 connection kit; CC170 with K24 connection kit; CC172, CC633 with K25 xxxconnection kit; CC179 without connection kit
The CC179 are Merc cables, so you don't need any adapter kits. It seem like the connection kits are to adapt non-Merc cables to Merc type remote ends. The others are Jonnyrudes, Morse and universal - all need kits. Only the Merc cable CC179 doesn't need an adapter.
One thing I don't see anything about is a neutral switch. It must have one.
EDIT - the Merc cable 179 is a Gen 1 cable. Pretty sure you will be OK.
