Hi, I've read a few posts about this topic on the forum. Here is my question, I am all set to cut the hole and will not have a second shot at it. The transom template has two numbers (X) in the 10 degree column, one for a standard install, and one below it for anti-cavitation plate level with the bottom of the boat. The boat is a heavy 19 footer with a 4.3L V6 and a DP-C drive. The difference between the heights is (363-351mm) 12mm. Any help appreciated, thanks!
