When two boats share the same hull type — in this case both the SunChaser 8520 4.0 2010 and the SunChaser 8522 CR 2009 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — SunChaser 8520 4.0 2010 at 20,3 ft versus SunChaser 8522 CR 2009 at 22,0 ft. At 185 lbs and 195 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The SunChaser 8522 CR 2009 tops out at 150 hp. Engine specs for the SunChaser 8520 4.0 2010 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The SunChaser 8522 CR 2009 is rated for 14 passengers, while the SunChaser 8520 4.0 2010 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SunChaser 8522 CR 2009 could be the deciding factor.
Bottom line: Choose the SunChaser 8522 CR 2009 if your priority is putting more people on the water — it handles 14 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The SunChaser 8520 4.0 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
