Using starting fluid on a 4 stroke outboard motor is generally not recommended unless as a last resort and very sparingly. Overuse can damage the engine internals due to the lack of lubrication in starting fluids, which can lead to premature wear. If your outboard motor is having trouble starting, it's better to troubleshoot fuel, spark, and air delivery issues first. Proper maintenance and seasonal checks can prevent situations where you might consider using starting fluid. Always consult your engine's manual or a professional before using starting fluid.
