Never opwned that big a motor with a tiller. All of my tiller motors were 15hp or less and every one of them had a lever to flip so I could pick the motor up half way and it'd catch. With smaller motors the T/T wouldnt be necessary. Ive fished Wateree where it joined the Congeree many a time and wouldnt see a reason for a tiller there either since it's 15' straight down on any bank. Santee could be a different situation since the upper end of the lake is slap full of stumps. I guess alot depends on how you drive and how big a hurry youre in. In water I dont know I'll idle if necessry to keep from tearing something up.
Health nuts are going to feel stupid someday, lying in hospitals dying of nothing.
