2005 Starcraft 2100 I/O Bowrider w/ 5.0L MerCruiser MPI V8 - Only 294.6 Hours
$19,990
5.0L MPI MerCruiser V8 • Only 294.6 Hours • Massive Rear Swim Platform • Huge Bow Seating Area • Bimini Top • Full Cover • Tandem Trailer Included
If you're looking for a clean, spacious family bowrider that can handle everything from tubing and skiing to sandbar days and sunset cruises, this 2005 Starcraft 2100 I/O deserves a serious look.
Starcraft has spent more than a century building some of America's most recognizable recreational boats, and the 2100 Series is a great example of why the brand has remained popular for generations. This 21-foot fiberglass bowrider combines a deep-V performance hull, a remarkably spacious interior, strong V8 power, and the comfort features families want for full days on the lake.
This particular boat stands out because of its overall condition and exceptionally low engine hours. With only 294.6 original hours, the MerCruiser 5.0L MPI V8 has seen relatively light use and gives this Starcraft the kind of smooth, dependable power that buyers actively search for in a larger family runabout.
Already equipped with an extended rear swim platform, Bimini top, Clarion marine audio system, full boat cover, bow filler cushion, and matching tandem-axle Starcraft trailer, this is a complete package that's ready to enjoy.
MerCruiser 5.0L MPI V8 Performance
Power comes from the highly desirable MerCruiser 5.0L MPI V8.
The Multi-Port Fuel Injection system delivers smooth starts, responsive throttle performance, and consistent operation while the V8 provides the torque needed for watersports and cruising with a full passenger load.
Performance Highlights
- MerCruiser 5.0L MPI V8
- Only 294.6 original hours
- Multi-Port Fuel Injection
- Strong hole-shot acceleration
- Excellent low-end and mid-range torque
- Smooth cruising performance
- Reliable electronic fuel delivery
- Excellent watersports capability
- Proven MerCruiser serviceability
- Easy parts availability
Whether you're pulling skiers, wakeboarders, kneeboarders, or tubes, this Starcraft has the power to do it confidently.
The V8 also makes a noticeable difference when the boat is loaded with passengers, coolers, and gear, allowing it to get on plane more easily than many smaller-engine packages.
Deep-V Starcraft Performance Hull
One of the reasons the Starcraft 2100 remains such a versatile family boat is its deep-V fiberglass hull.
The design gives the boat a sporty, responsive feel while still delivering the stability and comfortable ride families appreciate.
Hull Benefits
- Deep-V fiberglass hull
- Smooth ride through chop
- Stable cruising characteristics
- Responsive steering
- Predictable cornering
- Confident handling
- Easy planing
- Comfortable family ride
- Solid fiberglass construction
Whether you're running across open water or cruising slowly through a marina, the hull provides the balanced ride quality expected from a premium family runabout.
Massive Open-Bow Seating Area
One of the first things you'll notice stepping aboard is just how much room this boat has up front.
The bow seating area is exceptionally spacious for a 21-foot boat and creates a true lounge for passengers rather than simply a small forward seating section.
Bow Features
- Large wraparound bow seating
- Long lounge-style cushions
- Supportive backrests
- Bow filler cushion included
- Walk-through windshield
- Stainless grab handles
- Integrated cupholders
- Marine speakers
- Under-seat storage
- Deep, secure seating layout
The bow filler cushion can transform the area into an even larger lounging platform, making it perfect for relaxing at anchor or stretching out at the sandbar.
Spacious Family Cockpit
Move through the walk-through windshield and you'll find a cockpit designed around passenger comfort.
The seating arrangement offers plenty of room for family and friends while still leaving a wide, open walkway through the boat.
Interior Features
- Premium captain's bucket chair
- Matching passenger bucket seat
- Large rear wraparound seating
- Spacious open cockpit
- Snap-in marine carpeting
- Deep cockpit layout
- Stainless grab handles
- Multiple cupholders
- Large storage compartments
- Excellent passenger comfort
The layout gives everyone room to spread out without making the boat feel crowded.
Huge Rear Sun Pad
The rear sun pad is one of the standout features of the 2100.
It's wide, heavily padded, and provides a great place to relax while the boat is anchored.
Rear Lounge Benefits
- Massive padded sun deck
- Large lounging area
- Convenient engine compartment access
- Easy swim-platform access
- Excellent sandbar setup
- Great place to relax between watersports runs
Lift the sun pad and you'll find a spacious engine compartment with additional access for service and storage.
Extended Rear Swim Platform
The extended swim platform adds a tremendous amount of usable space at the stern.
Instead of a narrow boarding step, you get a large platform that's ideal for swimming, preparing watersports equipment, or simply sitting near the water.
Swim Platform Features
- Extended rear swim platform
- Stainless boarding ladder
- Non-skid surface
- Easy water access
- Watersports staging area
- Excellent sandbar setup
- Additional usable stern space
- Transom audio controls
For families that spend a lot of time swimming or tubing, this is one of the most valuable features on the boat.
Clarion Marine Audio System
This Starcraft is already equipped for long days on the water with a Clarion marine stereo system.
Audio Features
- Clarion marine stereo
- Multiple marine speakers
- Transom stereo remote
- Cockpit audio
- Bow audio
- Easy entertainment control
The transom remote is especially convenient when you're swimming or hanging out near the rear platform.
Bimini Top & Full Cover Included
This package includes both a Bimini top and a full boat cover.
Bimini Benefits
- Excellent shade coverage
- Increased comfort on hot days
- Easy deployment
- Fold-down storage
Full Cover Benefits
- Helps protect upholstery
- Reduces UV exposure
- Keeps debris out
- Helps preserve carpeting and interior surfaces
- Makes storage easier
Having both already included adds significant value to the package.
Comfortable Captain's Helm
The helm has a premium appearance thanks to its woodgrain-style dash and full analog instrumentation.
Helm Features
- Woodgrain dash package
- Full analog gauge cluster
- MerCruiser controls
- Tilt steering
- Comfortable captain's chair
- Excellent visibility
- Easy-to-read instrumentation
- Convenient switch layout
Everything is positioned within easy reach, making the boat comfortable and intuitive to operate.
Premium Starcraft Construction
Starcraft built the 2100 as a substantial family sport boat, and the quality is visible throughout.
Construction Highlights
- Deep-V fiberglass hull
- Premium marine upholstery
- Walk-through windshield
- Stainless hardware
- Snap-in carpeting
- Heavy-duty seating
- Large integrated storage areas
- Premium captain's chairs
- Quality gelcoat finish
- Excellent fit and finish
Even years later, this boat continues to show why Starcraft developed such a loyal following.
Matching Tandem-Axle Starcraft Trailer Included
Included with the sale is the matching Starcraft tandem-axle trailer.
Trailer Benefits
- Tandem-axle stability
- Proper hull support
- Easy transportation
- Convenient winter storage
- Multiple lake access
- Better highway towing characteristics
- Coordinated factory appearance
The trailer makes this a complete boat, motor, drive, and trailer package.
