The Stratos 170 Fish & Ski 2005 vs Stratos 180 FS 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.
Both boats share a closely matched power ceiling — 115 hp for the Stratos 170 Fish & Ski 2005 and 135 hp for the Stratos 180 FS 2006. 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 — 26 gal and 26 gal — so range won't be a tiebreaker here.
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 Stratos 180 FS 2006 and its 135-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Stratos 170 Fish & Ski 2005 with its 115-hp rating is the more economical daily driver.
