Hi Eugene. The existing steering cable worked fine (only five inches of setback).
Performance: With the initial install, I raised the motor 5/8". My WOT speed and RPM numbers are about the same. Hole shot is improved and so is the overall handling. I still have another 200-300 rpm to go before redline, but I don't want to raise the motor any further without a water pressure gauge. They were out of them at BPS when I was last there. So, as soon as I get the water pressure gauge installed, I'll start to tweak the height a bit.
I am going to put a hydrofoil on as well. The jackplate acts like a big scoop when coming off plane as the stern squats. It can put a bunch of water on the back deck, so I need to start landing a little flatter.
I've got pictures of everything I did, and will publish it all when the final numbers are in.
