A Craftsman 21759464 4.5-hp outboard motor typically lasts 10 to 15 years with normal recreational use and consistent maintenance. In saltwater, poor fuel storage, or infrequent servicing, lifespan drops; with careful care, many motors run longer.

• Cooling system care: a clogged water intake or worn impeller leads to overheating and rapid wear.
• Fuel quality and storage: ethanol fuel left sitting causes varnish, clogged carburetor jets, and hard starting.
• Corrosion exposure: saltwater use without thorough flushing and rinsing shortens life.
• Oil and lubrication habits: correct oiling and gearcase lube changes prevent internal damage.
• Operating style: long wide-open-throttle runs and frequent overheating events reduce engine life.

• Flush cooling passages after every outing (especially saltwater).
• Stabilize fuel for storage; run the engine to pull treated fuel into the carburetor.
• Inspect the telltale stream; address weak flow immediately.
• Change lower unit (gearcase) lubricant on schedule; check for milky oil (water intrusion).
• Inspect/replace spark plug(s) and fuel lines as needed.

Outboards usually fail early from overheating or fuel-system neglect, not from “old age.” Staying ahead of cooling flow and fuel storage protects the powerhead and keeps parts replacement predictable.
