For trailering, the Tahoe Boats Q5 S 2003 has the edge at 2 494 lbs dry weight versus 3 500 lbs for the Tahoe Boats Q8i 2007.

The Tahoe Boats Q8i 2007 measures 102" wide, compared to 96" for the Tahoe Boats Q5 S 2003. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The Tahoe Boats Q8i 2007 has the bigger tank at 54 gallons, versus 28 gallons on the Tahoe Boats Q5 S 2003. That 26-gallon difference translates to roughly 78–130 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes - both the Tahoe Boats Q5 S 2003 and the Tahoe Boats Q8i 2007 are built by Tahoe Boats. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Tahoe Boats Q5 S 2003 vs Tahoe Boats Q8i 2007: Same Brand, Different Boat

The Tahoe Boats Q5 S 2003 vs Tahoe Boats Q8i 2007 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 Tahoe Boats Q8i 2007 tops out at 320 hp. Engine specs for the Tahoe Boats Q5 S 2003 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Tahoe Boats Q8i 2007 carries 54 gallons versus 28 gallons in the Tahoe Boats Q5 S 2003. 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 Tahoe Boats Q8i 2007 is rated for 10 passengers, while the Tahoe Boats Q5 S 2003 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tahoe Boats Q8i 2007 could be the deciding factor.

The Tahoe Boats Q5 S 2003 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
