The Command Thrust models use the same bigger gearcase housing as the Mercury 150 FourStroke, but with an all-new 2.38:1 ratio ideally suited for pontoons and heavier boats. Itâs the first true oversized gearcase in the industry for outboards in this horsepower range.
I set my trim tab straight ahead, if I use one at all, and use trim to neutralize the steering torque instead. With many of the modern propellers, on Mercurys at least, a trim tab anode is not even used, and is replaced by a flat plate anode, to avoid prop interference. The need for trim tab adjustment for steering torque is now pretty much replaced by a good power trim system. Steering pull varies based on power trim setting.
