Counter-rotation is only a consideration for those boating enthusiasts who have more than a single motor powering their water craft. With two Force outboard propellers, however, boaters may find that steering becomes an issue. When this happens it is usually an indication that both Force outboard props are rotating in the same direction. This causes the boat to veer off course and requires the operator to constantly pay close attention to navigation, making small course corrections as needed. When weather conditions produce high winds or a lot of wave action, the problem can be magnified.

Using Force boat propellers with counter-rotation can solve most of the issue. Counter-rotation simply means that if one propeller turns in a right-handed direction, the other one will turn in a left-handed direction. Across all ranges of RPM, counter-rotation is effective at improving the navigational performance of the water craft. This is due to the fact that as the clockwise rotation of one propeller causes the boat to list slightly to the right, the counter-clockwise rotation of the other propeller will produce a listing force toward the right. In the aggregate, the two forces largely cancel each other out, allowing the boat operator to enjoy steering that is much more true.

Counter-rotation has really come into its own during the last decade or so. This is because during that time, it became more common for manufacturers to produce recreational water craft that were large enough to truly need a twin engine set up.
