The Monterey M3 MSX 2012 vs Monterey M4 2020 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 — Monterey M3 MSX 2012 at 23,8 ft versus Monterey M4 2020 at 23,1 ft. Weight tells a clearer story for trailering families: the Monterey M4 2020 tips the scales at 4 500 lbs — 4 455 lbs less than the Monterey M3 MSX 2012 at 45 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 320 hp for the Monterey M3 MSX 2012 and 300 hp for the Monterey M4 2020. 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 — 5 gal and 5 gal — so range won't be a tiebreaker here.
