I did a couple of times, only to find out that it let the wind push the back end of the boat around. Now, even though my boat is a "bass boat", it drifts very easily in almost no wind. That makes staying on a concise course a little tricky, sometimes, even when the big motor is down ... let alone when trimmed up.

One trick I did learn, when having the big motor trimmed down, was to put the motor "in gear" so as to not have the prop turning. Why would I do that, you ask, since that would create a little more drag ?? Well, my answer to that is .... if for some reason you had to make a quick turn, which could put your lines in contact with the prop, it's less likely that the lines will get wrapped around the stationary prop than a prop that's turning (due to being in neutral).
