What are the different parts of a boat called?
Most boats use the same standard names for major sections and hardware; for a Craftsman 217586751 7.5-hp outboard motor setup, these terms help you identify what you’re looking at and describe the right area when troubleshooting steering, propulsion, or hull-related issues. See how to find your appliance model number (and what it means for parts) for tips on confirming the exact model before ordering.
- Bow: front of the boat
- Stern: rear of the boat
- Port: left side when facing forward
- Starboard: right side when facing forward
- Hull: main body that floats
- Deck: top surface you stand or sit on
- Transom: flat rear wall where many outboard motors mount
- Keel: center “spine” along the bottom that helps tracking and stability
- Gunwale: top edge of the hull sides
- Helm: steering station (wheel/tiller, controls, gauges)
- Rudder (on inboard/sail boats): steering blade in the water (many small outboards steer by turning the motor instead)
| Part | What it does | Why you care |
|---|---|---|
| Propeller | Pushes water to move the boat | Damage causes vibration, poor speed, and cavitation |
| Skeg | Fin below the prop area | Protects the lower unit and helps tracking |
| Throttle/shift controls | Set speed and gear | Misadjustment can cause hard shifting or stalling |
Using the correct terms helps us match the right boating parts category (for example, transom mounting hardware vs. propeller hardware) and speeds up diagnosis when you describe symptoms like “vibration at the stern” or “pulling to port.”

Where can I get Craftsman replacement parts?
You can get replacement parts for your Craftsman 217586751 7.5-hp outboard motor from Sears PartsDirect and other authorized retailers; the key is matching the exact model number and confirming the engine manufacturer so the part fits and performs correctly.
- Sears PartsDirect (search by model number 217586751 for boating parts diagrams and part lookups)
- Craftsman’s official parts channels (when available for your product line)
- Major retailers that carry Craftsman parts (online and in-store)
- Marine and small-engine parts suppliers (helpful for ignition, fuel, and cooling components)
- Reputable aftermarket sellers (use extra care to match specs)
For outboard motors, “Craftsman” is the brand on the product, but many engine components are built by an engine manufacturer. Before ordering, we recommend confirming:
- Exact model number: 217586751 (use the full number, not a partial)
- Engine ID tag details: model, serial, and sometimes a code for the engine maker
- Part category: fuel system, ignition, recoil starter, lower unit, cooling, controls
- Electrical specs: voltage, connector style, wire gauge (when applicable)
- Mounting and fit: bolt pattern, shaft length, gasket shape
| Option | Best for | What to watch |
|---|---|---|
| OEM/authorized | Direct-fit replacements | Availability and price |
| Aftermarket | Cost savings, older models | Verify dimensions, materials, and return policy |
Using the correct part for a 7.5-hp outboard motor protects reliability and safety on the water; mismatched fuel or ignition parts can cause hard starting, stalling, or overheating.

What is the average lifespan of 217586751?
A Craftsman 217586751 7.5-hp outboard motor typically lasts 10 to 15 years with normal recreational use and consistent maintenance (fresh fuel, correct oil mix if applicable, cooling system care, and corrosion prevention). Heavy saltwater use and poor storage shorten lifespan.
- Maintenance frequency: regular tune-ups, gearcase service, and cooling checks
- Fuel quality and storage: stabilized fuel, clean tank/lines, drained carburetor for storage
- Operating conditions: saltwater exposure, sand/silt, overheating events
- Usage pattern: long wide-open-throttle runs vs. moderate cruising
- Winterization and storage: fogging, flushing, dry storage, covered ventilation
| Interval | What to do | Why it matters |
|---|---|---|
| Every outing | Check telltale stream, inspect prop, look for fuel leaks | Prevents overheating and damage |
| Every season | Replace spark plug(s), inspect fuel lines, clean/inspect carburetor | Improves starting and protects the powerhead |
| Annually | Change lower unit gear oil, inspect water pump impeller | Prevents gear wear and cooling failure |
| Before storage | Stabilize fuel, fog cylinders, flush cooling passages | Reduces corrosion and varnish buildup |
- Low compression, hard starting, or frequent plug fouling
- Overheating, weak telltale, or repeated impeller failures
- Metal flakes or milky oil in the lower unit gear oil
- Persistent fuel leaks, cracked hoses, or carburetor flooding
- Excessive corrosion around fasteners, mounts, or exhaust housing
Outboard lifespan is driven more by cooling, lubrication, and corrosion control than by age alone. Staying ahead of water pump and gearcase service prevents the most expensive failures.
