Alumacraft Invader 185 2002 vs Alumacraft VS170 2007 — Same Brand, Different Boat

The Alumacraft Invader 185 2002 vs Alumacraft VS170 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 power gap is worth calling out. Rated to 135 hp, the Alumacraft Invader 185 2002 has a 65-hp advantage over the Alumacraft VS170 2007's 70-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Alumacraft Invader 185 2002 carries 27 gallons versus 16 gallons in the Alumacraft VS170 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 4 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Alumacraft Invader 185 2002 and its 135-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumacraft VS170 2007 with its 70-hp rating is the more economical daily driver.

Alumacraft Invader 185 2002 vs Alumacraft VS170 2007 — Common Questions

Which is easier to trailer — the Alumacraft Invader 185 2002 or the Alumacraft VS170 2007?
For trailering, the Alumacraft Invader 185 2002 has the edge at 13 lbs dry weight versus 852 lbs for the Alumacraft VS170 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Alumacraft Invader 185 2002 is rated to a maximum of 135 hp, giving it the larger power ceiling. The Alumacraft VS170 2007 tops out at 70 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Alumacraft Invader 185 2002 is Coast Guard rated for 4 passengers, while the Alumacraft VS170 2007 is certified for 4. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Alumacraft Invader 185 2002 measures 92" wide, compared to 74" for the Alumacraft VS170 2007. 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.
Which boat has the larger fuel tank — the Alumacraft Invader 185 2002 or the Alumacraft VS170 2007?
The Alumacraft Invader 185 2002 has the bigger tank at 27 gallons, versus 16 gallons on the Alumacraft VS170 2007. That 11-gallon difference translates to roughly 33–55 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumacraft Invader 185 2002 and Alumacraft VS170 2007 from the same manufacturer?
Yes — both the Alumacraft Invader 185 2002 and the Alumacraft VS170 2007 are built by Alumacraft. 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.
