Good to hear you are going to test it this weekend. I'd like to hear your results. We havn't had ours in the water for a year or so, it's been an ongoing project, but the last we had it in the water our fuel pump was going out on us. Saying that, we had somewhere in the 28 knots range around 3900 rpm. I don't recall our fuel burn, we have a flow meter installed, just don't remember what it read.
Our grady has been a 3 year project and we are going to wrap it up this winter and have it ready to fish come May 1 when grouper opens back up.
I'd like to hear your numbers on the upcoming run.
Thanks
