I just got back from Lake Guntersville where I had a decent chance to really run the boat. With the prop shaft 3 1/2" below pad I was turning the 25p Raker II 6000rpms and was getting 73.1 mph on my 250 HO. I even adjusted the jack plate to where it was 2 1/2 mph and it didn't make any difference in the performance other than that water pressure went down some.
I also seem to be loosing bite when I get on plane. I don't understand that. Can someone explain that. Do I need to get the 27 Tempest.
