Mr. Fisherman,
When I got my C-Dory it came with 4 Fish-On bases bolted on. I Changed them out for Scotty bases. The holes were close enough that I only had to enlarge two holes slightly to make the spacing right. As I recall, the vertical spacing was identical but the horizontal holes were slightly too close together ( if that makes any sense). I agree absolutely that the Scotty is heads and shoulders above the Fish-On.
