Both the Lund 1700 Pro Sport Vazer 2009 and the Lund 1900 Pro-V SE 2007 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Lund 1700 Pro Sport Vazer 2009 at 17,0 ft versus Lund 1900 Pro-V SE 2007 at 19,0 ft. At 1 750 lbs and 1 730 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 225 hp, the Lund 1900 Pro-V SE 2007 has a 125-hp advantage over the Lund 1700 Pro Sport Vazer 2009's 100-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 1900 Pro-V SE 2007 carries 45 gallons versus 20 gallons in the Lund 1700 Pro Sport Vazer 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 5 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 Lund 1900 Pro-V SE 2007 and its 225-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 1700 Pro Sport Vazer 2009 with its 100-hp rating is the more economical daily driver.
