The Princecraft Pro 164 SS 2006 vs Princecraft Pro 166 2008 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.
On paper these two are close siblings in the size department — Princecraft Pro 164 SS 2006 at 16,0 ft versus Princecraft Pro 166 2008 at 16,0 ft. At 985 lbs and 1 009 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.
Both boats share a closely matched power ceiling — 90 hp for the Princecraft Pro 164 SS 2006 and 90 hp for the Princecraft Pro 166 2008. 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. Both carry nearly identical fuel loads — 28 gal and 28 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Princecraft Pro 166 2008 is rated for 6 passengers, while the Princecraft Pro 164 SS 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Pro 166 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Pro 164 SS 2006 comes in at 11 lbs per hp versus 11 lbs per hp for the Princecraft Pro 166 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Princecraft Pro 166 2008 if your priority is putting more people on the water — it handles 6 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Princecraft Pro 164 SS 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
