Matt, I've had 25hps almost my whole life. THere is a shallow running mode that has latch that kicks out under the motor that rests against the motor part that goes over the transom. This holds the motor at about 1/4 tilt. This gave you PLENTY of clearence to tow your motor without worries of dragging the skeg. What most do is put a bungy cord from one handle on the transom across the back of the motor to the other handle on the transom. If the bungy cord was too big I tied knots in it until it fit tight to keep it from bouncing.
