shown struck through where we beat it. Parts marked In Stock ship in 1 to 2 days — from our shelf here, or shipped direct to you from Sierra’s warehouse. Backorder Now means neither we nor Sierra hold one right now: you can place the order and Sierra ships it direct as soon as it is back in stock.
Engine applications come from Sierra’s own catalog: model code, year range, horsepower and serial-number window. Horsepower comes before model because Sierra’s model codes identify rigging rather than names an owner recognises — Johnson/Evinrude alone has over 11,000. Around two thirds of Sierra’s catalog — oils, gauges, hoses, sanitation — fits no particular engine and is found by category on the browse-all tab instead.
