I have pulled off the side from the front before, just make sure your holders are strong and tight. I also have a 90hp and found it takes a 48" driftsock or bigger to slow the boat down to the 1.5 -2.0 range. I use a water ski harness that I hook it to so that it drags straight off the back when I use the big motor. The motor runs fine but I clear her on out on the way back to the ramp just to be sure I still prefer the troller with planer boards just to be sneaky.
