There are a few things you can do to lower your pontoon motor. One is to adjust the trim tabs on the back of the boat. This will help the boat sit level in the water and make it easier to maneuver. Another thing you can do is remove any weight from the front of the boat, such as coolers or chairs. This will help the boat ride higher in the water and make it easier to steer. Finally, you can try moving the engine forward or backward in its mount. This will change the center of gravity of the boat and may make it easier to control.
