I look at the pictures and videos of the boats you guys all have, and they all appear to made of fiberglass.  Here, in Alberta where I go boating, most of the boats used in the rivers are constructed of aluminum.  I used to run a fiberglass boat a long time ago, and it was okay, but for many years now I have been running an aluminum hull.  I didn't ever weigh the fiberglass boat to know what it weighed, but I know the aluminum one I have that the bare hull weighs 600 lbs.  Even with a big block engine, pump, and fuel in the tanks, it still weighs around 2000 lbs, or a little less.  I may be wrong, but I think the aluminum hulls are lighter than the fiberglass.  What kind of speeds can you guys get out of these boats?  What cut of impellors do you use.  I use an A or even an A2 with a Dominator pump. When I go boating, I like to cruise around 4000 or so, and I do this for hours sometimes. The engine seems to be really happy at that speed, and the relatively light weight gives me a cruising speed of 60- 65 MPH. Just a few questions to satisfy my curiosity.  I don't normally take this boat to any lake, because the lakes around here are small, and just buzzing from one end to the other isn't very much fun.
