I have a 2004 procraft with a 2012 150 optimax, I’m currently running a 21p laser with a 4 inch jackplate, at WOT running 5,000 rpm’s 50mph but I am running out of trim and not getting enough now lift, would add in a 6 or 8 inch jackplate instead fix my issues?? I tried a few different props as well to no avail. Thanks
