The G3 Boats HP 170 2007 vs G3 Boats PB 20 Fish 2004 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.

Size is the most obvious dividing line here. The G3 Boats HP 170 2007 measures 17,0 feet overall (2007), giving it roughly 15,0 additional feet of deck space compared to the G3 Boats PB 20 Fish 2004 at 2,0 feet (2004). Weight tells a clearer story for trailering families: the G3 Boats HP 170 2007 tips the scales at 118 lbs — 103 lbs more than the G3 Boats PB 20 Fish 2004 at 15 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.

Both boats share a closely matched power ceiling — 115 hp for the G3 Boats HP 170 2007 and 100 hp for the G3 Boats PB 20 Fish 2004. 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 — 21 gal and 23 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The G3 Boats PB 20 Fish 2004 is rated for 11 passengers, while the G3 Boats HP 170 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the G3 Boats PB 20 Fish 2004 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The G3 Boats PB 20 Fish 2004 comes in at 0 lbs per hp versus 1 lbs per hp for the G3 Boats HP 170 2007. 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.
