When two boats share the same hull type — in this case both the SunChaser 8520 4.0 2010 and the SunChaser Cruise 8524 Lounger 2013 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?
Size is the most obvious dividing line here. The SunChaser Cruise 8524 Lounger 2013 measures 25,8 feet overall (2013), giving it roughly 5,6 additional feet of deck space compared to the SunChaser 8520 4.0 2010 at 20,3 feet (2010). At 185 lbs and 255 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 Cruise 8524 Lounger 2013 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.Fuel capacity breaks the other way: the SunChaser 8520 4.0 2010 carries 24 gallons versus 3 gallons in the SunChaser Cruise 8524 Lounger 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The SunChaser Cruise 8524 Lounger 2013 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 Cruise 8524 Lounger 2013 could be the deciding factor.
Bottom line: Choose the SunChaser Cruise 8524 Lounger 2013 if your priority is putting more people on the water — it handles 14 passengers and at 25,8 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.
