The ThunderJet 176 Eco Jet 2012 is a deep-V design and the ThunderJet Havasu 2009 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - ThunderJet 176 Eco Jet 2012 at 17,6 ft versus ThunderJet Havasu 2009 at 20,0 ft. Weight tells a clearer story for trailering families: the ThunderJet Havasu 2009 tips the scales at 2 600 lbs - 900 lbs less than the ThunderJet 176 Eco Jet 2012 at 1 700 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.

The ThunderJet Havasu 2009 tops out at 250 hp. Engine specs for the ThunderJet 176 Eco Jet 2012 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Havasu 2009 carries 50 gallons versus 34 gallons in the ThunderJet 176 Eco Jet 2012. 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 ThunderJet Havasu 2009 is rated for 6 passengers, while the ThunderJet 176 Eco Jet 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Havasu 2009 could be the deciding factor.
