i agree with the theory about conditioning the fish to spook when the hear/feel the motor racing in on them. another thing i wonder is this, are there as many fish as there used to be? now im not saying there arent any fish left, what i am asking is the population down compared to what it has been. you hear it over and over , people saying they just cant locate the big schools on the graph like they used to. i have seen a couple big schools lately as opposed to doens of huge schools in the past.
look at it this way, if you deer hunt a farm that has 10 bucks that call it home, you are more likely to see a buck than if youre hunting a farm that has 2 bucks on it. so.....if there arent as many big schools as there once were, the chances of sitting in one spot and seeing a big school jump while youre there,

just a shot in the dark, i dont have any data to support or refute this idea
