The MirroCraft 1615-O Outfitter 2004 vs MirroCraft 1628 Holiday 2004 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.
Both boats share a closely matched power ceiling — 40 hp for the MirroCraft 1615-O Outfitter 2004 and 60 hp for the MirroCraft 1628 Holiday 2004. 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.
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 MirroCraft 1628 Holiday 2004 and its 60-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the MirroCraft 1615-O Outfitter 2004 with its 40-hp rating is the more economical daily driver.
