Hey guys, on this 1990 stratos with a 1990 evinrude 150 and a six inch jack plate, this jack plate was put on the boat just before I bought it and not set, I really don't know much about jack plates or how to set them up. My question is how to do this, is their a starting point? And how high should I be trimming the motor up I really need help, I have been given some answers but I really don't understand what they mean I just don't know what I'm looking for. I first set the plate as high as it would allow but it seems as if the prop is washing out in turns, (water pressure is fine) do I have the engine set to high or is it that I'm trimming it to high. I was told depending on what prop I have that I should not have a rooster tail bigger then 24" but since I raised the engine it shoots one much higher then that. I'm not sure what pitch the prop is all I know is that it is a raker brand and it is a three blade. Please help thanks
