An outboard or sterndrive gear case's skeg gives a lot of directional stability and steering comfort. A broken or damaged skeg, whether caused by running aground or some other land-based tragedy, has a negative impact on handling. A welder may be able to fix your skeg in some circumstances. The skeg functions as a precision rudder, allowing your boat to be turned precisely and safely by the engine. High-performance boats, such as bass boats, require this function since the skeg plays a vital part in steering on the plane. The Thickness of our Evinrude/Johnson Magnum 150-225 hp 2003 (70-1225) is 1/2 inch. Key features: Creates resistance to the wind's turning effect, causing the boat to go straight. Protects your propeller against objects in the water, causing it to snag and become stuck. Product Description: SKU: 70-1225 Weight: 1.50 LBS Quantity: 1 Brand: Skeg Depot Thickness: 1/2
