I put a 5" manual jack plate on my 170 last year and am finally getting to mess with it's set up.
I have heard to set it as low as it will go an lift it 1/2" at a time till you start to loose speed or waterpressure then back it down till you get the best hole shot and top end without loosing water pressure.
I have also heard that a good starting point is 3" below the pad. Ok, now I am a bit dense at times:blink:, So what is 3" below the pad. The top of the prop? or the prop shaft??
Wouldn't the top of the prop be out of the water if I set the shaft only 3" down. 13 1/2" dia pro divided by 2 equals 6 1/4". Wouldn't the prop be 3" out of the water?? I know I missing something hear:unsure:
