When two boats share the same hull type — in this case both the Lund 1625 Rebel XL SS 2008 and the Lund 1725 Pro Guide 2009 are modified vee designs with aluminum construction — 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?
Both boats share a closely matched power ceiling — 75 hp for the Lund 1625 Rebel XL SS 2008 and 75 hp for the Lund 1725 Pro Guide 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Lund 1725 Pro Guide 2009 carries 27 gallons versus 19 gallons in the Lund 1625 Rebel XL SS 2008. 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 1725 Pro Guide 2009 is rated for 5 passengers, while the Lund 1625 Rebel XL SS 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1725 Pro Guide 2009 could be the deciding factor.
Bottom line: Choose the Lund 1725 Pro Guide 2009 if your priority is putting more people on the water — it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Lund 1625 Rebel XL SS 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
