I do not have a jack plate on my 2000 Nitro with 175ProSx. I decided to raise the engine up one bolt hole to see what it would do, hoping for more top end speed. I took it out and it was slow to get out of the hole. I filled the live well 3/4 way and it would not get out of the hole unless someone was sitting on the front deck. Could raising the engine that 1 inch make that much difference?
