When two boats share the same hull type — in this case both the Starcraft Marine SF 1620 SS 2010 and the Starcraft Marine SF DLX 168 Pro Troller 2013 are modified vee 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?
Both boats share a closely matched power ceiling — 40 hp for the Starcraft Marine SF 1620 SS 2010 and 60 hp for the Starcraft Marine SF DLX 168 Pro Troller 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Starcraft Marine SF 1620 SS 2010 is rated for 6 passengers, while the Starcraft Marine SF DLX 168 Pro Troller 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine SF 1620 SS 2010 could be the deciding factor.
Bottom line: Choose the Starcraft Marine SF 1620 SS 2010 if your priority is putting more people on the water — it handles 6 passengers and at 16,2 ft it has the deck room to back that rating up comfortably. The Starcraft Marine SF DLX 168 Pro Troller 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
