Well just to follow up and provide a solution to anyone seeing this in a google search I finally got the boat on the water with two fuel pressure gauges hooked up and somehow the boat ran perfect for the first time in awhile. The only thing that I had done was attaching and reattaching the spark plug wires when I was checking for any cracked ones or any crunchy feeling ones that was suggested to me. I had pulled all 8 plug wires at the distributor previously and had pulled 4 off of the plugs at the motor but something after pulling the other 4 seems to have fixed my issue. I can't believe how much time I spent on this but next time I'll be sure to check my plugs and wires before I get this deep.
To add to the debate of fuel pressure, I have read in my Seloc manual that 3-7 psi was acceptable and I'm basically showing 6-10 psi. Maybe the 2 high pressure gauges and 1 low pressure gauge are all off by exactly the same amount but I'm thinking 6-10 psi is acceptable for my boat. I never saw it drop below 5.5-6.0 under the largest load I could give it and it's running perfect now. No hesitation, no surging, planes out much quicker, and finally achieving WOT of 4400 RPM and 47 mph like it used to.
Thank you for all of your suggestions, I now know my simple little fuel system inside and out.
