RE: Prop mods
My take on this is its not so much the prop mods as boat setup. Many of the prop numbers being talked about here are too big for me and might produce a good terminal speed after a 100 metres on some choppy water but for racing are a waste of time. They will run if I lift the strut a lot but then the boat handling is ugly. I like to run high rpm on my monos and a modded 7016/2 gives the best top speed on the GPS but a stock 7015/3 gives me the best laptimes by far, good acceleration out of the corners and good speed but the setup on the strut is completely different. To get the revs on the 7015/3 compared to the 7016/2 I have to lift the strut about 3mm or so and give it a touch of down angle (negative?). I don't use tabs but if the boat leans to the right I tilt the bottom of the rudder out to the right by a tiny amount (looking from the back of the boat)and that levels it up.
