I pulled the trigger and had a new 115 vmax installed on my mako, picked it up today and drove right to the local lake. It was my wife's idea to get a 4 stroke and so far it was worth every penny.so far I clocked it at 52 mph on GPS with my wife and I in it and a full tank of fuel. I'm very happy with the performance and how smooth and quiet it is and the both of us were grinning ear to ear as soon as we hit the water. I'll figure out how to post pictures and get some up
