Detailed Evaluation & Buyer Recommendation

Cobalt Boats 23SC 2021 vs Cobalt Boats 336 2013 — Same Brand, Different Boat

The Cobalt Boats 23SC 2021 vs Cobalt Boats 336 2013 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.

The Cobalt Boats 336 2013 tops out at 2 hp. Engine specs for the Cobalt Boats 23SC 2021 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Cobalt Boats 336 2013 carries 154 gallons versus 59 gallons in the Cobalt Boats 23SC 2021. 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 Cobalt Boats 336 2013 is rated for 10 passengers, while the Cobalt Boats 23SC 2021 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Cobalt Boats 336 2013 could be the deciding factor.

The Cobalt Boats 23SC 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
