The Lund 1650 Renegade Sport 2010 vs Lund 1800 Fisherman OB 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.
The power gap is worth calling out. Rated to 175 hp, the Lund 1800 Fisherman OB 2004 has a 115-hp advantage over the Lund 1650 Renegade Sport 2010's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lund 1650 Renegade Sport 2010 carries 19 gallons versus 4 gallons in the Lund 1800 Fisherman OB 2004. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Lund 1650 Renegade Sport 2010 is rated for 5 passengers, while the Lund 1800 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 1650 Renegade Sport 2010 could be the deciding factor.
Bottom line: Choose the Lund 1650 Renegade Sport 2010 if your priority is putting more people on the water — it handles 5 passengers and at 16,5 ft it has the deck room to back that rating up comfortably. The Lund 1800 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.
