Have a 27 gdsd on a 15/42 alweld . With a brand new prop it doesn’t throw much of a rooster tail at all. The more I wore the prop down the more it would throw . IMO on my boat I don’t wana see much of a rooster tail. As for as speed goes check what rpm your turning up with 2 guy and a hunting load mines will run 3550 range 25mph. Also move shit around in your boat and see if that helps. I put as much as I can all the way to the front. Definitely by my self. Which I don’t weigh much. The more weight I have up front the better it runs .
