Lund SSS,
What motor are you running on your Lund? I have an 05 prov 19' ifs and thinking of switching to a 4 blade prop for better hole shot and quicker time on plane when full of gear and people. I have a Yamaha f150 and 19" pitch prop and it takes a long time to get on plane ... Especially on the Great Lakes when it's choppy out. Heard you have to down size a pitch or two when switching to a 4 blade.
