The Sanpan SP 2500 LE I/O 2004 vs Sanpan SP2500 RE 3-Gate I/O 2006 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.
On paper these two are close siblings in the size department — Sanpan SP 2500 LE I/O 2004 at 25,0 ft versus Sanpan SP2500 RE 3-Gate I/O 2006 at 25,0 ft.

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 carry nearly identical fuel loads — 34 gal and 37 gal — so range won't be a tiebreaker here.
