SunChaser 8520 4.0 2007 vs SunChaser 8520 CR 2009 — Same Brand, Different Boat

The SunChaser 8520 4.0 2007 vs SunChaser 8520 CR 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — SunChaser 8520 4.0 2007 at 2,0 ft versus SunChaser 8520 CR 2009 at 2,0 ft. Weight tells a clearer story for trailering families: the SunChaser 8520 CR 2009 tips the scales at 1 875 lbs — 1 690 lbs less than the SunChaser 8520 4.0 2007 at 185 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 115 hp, the SunChaser 8520 CR 2009 has a 25-hp advantage over the SunChaser 8520 4.0 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The SunChaser 8520 4.0 2007 comes in at 2 lbs per hp versus 16 lbs per hp for the SunChaser 8520 CR 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the SunChaser 8520 CR 2009 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the SunChaser 8520 4.0 2007 with its 90-hp rating is the more economical daily driver.

SunChaser 8520 4.0 2007 vs SunChaser 8520 CR 2009 — Common Questions

Which is the larger boat — the SunChaser 8520 4.0 2007 or the SunChaser 8520 CR 2009?
The SunChaser 8520 CR 2009 is the longer of the two at 2,0 feet overall. The SunChaser 8520 4.0 2007 comes in at 2,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the SunChaser 8520 4.0 2007 or the SunChaser 8520 CR 2009?
For trailering, the SunChaser 8520 4.0 2007 has the edge at 185 lbs dry weight versus 1 875 lbs for the SunChaser 8520 CR 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The SunChaser 8520 CR 2009 is rated to a maximum of 115 hp, giving it the larger power ceiling. The SunChaser 8520 4.0 2007 tops out at 90 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The SunChaser 8520 4.0 2007 is Coast Guard rated for 12 passengers, while the SunChaser 8520 CR 2009 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The SunChaser 8520 4.0 2007 has a better power-to-weight ratio at 2 lbs per hp compared to 16 lbs per hp for the SunChaser 8520 CR 2009. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the SunChaser 8520 4.0 2007 and SunChaser 8520 CR 2009 share an 102 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the SunChaser 8520 4.0 2007 and SunChaser 8520 CR 2009?
Both boats carry similar fuel loads — 24 gallons and 24 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the SunChaser 8520 4.0 2007 and SunChaser 8520 CR 2009 from the same manufacturer?
Yes — both the SunChaser 8520 4.0 2007 and the SunChaser 8520 CR 2009 are built by SunChaser. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
