The Lund 1700 Fisherman OB 2004 vs Lund 1775 Impact SS 2011 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 power gap is worth calling out. Rated to 150 hp, the Lund 1700 Fisherman OB 2004 has a 25-hp advantage over the Lund 1775 Impact SS 2011's 125-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 27 gal and 27 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Lund 1775 Impact SS 2011 is rated for 5 passengers, while the Lund 1700 Fisherman OB 2004 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1775 Impact SS 2011 could be the deciding factor.
Bottom line: Choose the Lund 1775 Impact SS 2011 if your priority is putting more people on the water - it handles 5 passengers and at 17,8 ft it has the deck room to back that rating up comfortably. The Lund 1700 Fisherman OB 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
