When two boats share the same hull type — in this case both the Starcraft Marine 168 Pro Troller 2011 and the Starcraft Marine Limited 185 I/O Sport 2012 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?
On paper these two are close siblings in the size department — Starcraft Marine 168 Pro Troller 2011 at 16,0 ft versus Starcraft Marine Limited 185 I/O Sport 2012 at 18,2 ft. Weight tells a clearer story for trailering families: the Starcraft Marine 168 Pro Troller 2011 tips the scales at 875 lbs — 720 lbs more than the Starcraft Marine Limited 185 I/O Sport 2012 at 155 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 220 hp, the Starcraft Marine Limited 185 I/O Sport 2012 has a 160-hp advantage over the Starcraft Marine 168 Pro Troller 2011's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Limited 185 I/O Sport 2012 is rated for 8 passengers, while the Starcraft Marine 168 Pro Troller 2011 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 Limited 185 I/O Sport 2012 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Limited 185 I/O Sport 2012 if your priority is putting more people on the water — it handles 8 passengers and at 18,2 ft it has the deck room to back that rating up comfortably. The Starcraft Marine 168 Pro Troller 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
