SGX, AB black 45 muffled pipe, 1462 #2 profile. David did mod the AA45 and it is VERY strong. It has a fair amount of 60% through it with zero issues at all. I had just changed from running a V955/3 to the 1462 right before the run in this video. The tail end hop was because I had adjusted the strut for the 1462 and missed the perfect angle just a bit. Of course I did not forget to grease the shaft but this run was at the end of the day and I was pushing it. The boat had made many strong runs earlier and the AA45 is impressive.
