Lowe Boats FM 1625 SC 2021 vs Lowe Boats FM 1775 SC 2021 — Same Brand, Different Boat

The Lowe Boats FM 1625 SC 2021 vs Lowe Boats FM 1775 SC 2021 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 — Lowe Boats FM 1625 SC 2021 at 16,5 ft versus Lowe Boats FM 1775 SC 2021 at 17,9 ft. Weight tells a clearer story for trailering families: the Lowe Boats FM 1775 SC 2021 tips the scales at 1 267 lbs — 247 lbs less than the Lowe Boats FM 1625 SC 2021 at 1 020 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.

The power gap is worth calling out. Rated to 115 hp, the Lowe Boats FM 1775 SC 2021 has a 25-hp advantage over the Lowe Boats FM 1625 SC 2021's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lowe Boats FM 1625 SC 2021 carries 12 gallons versus 2 gallons in the Lowe Boats FM 1775 SC 2021. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe Boats FM 1775 SC 2021 comes in at 11 lbs per hp versus 11 lbs per hp for the Lowe Boats FM 1625 SC 2021. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both the Lowe Boats FM 1625 SC 2021 and Lowe Boats FM 1775 SC 2021 are trailerable, which is a big part of the appeal at this size. You can store either at home, hitch up on a whim, and launch wherever the water looks good.

Bottom line: Performance buyers should lean toward the Lowe Boats FM 1775 SC 2021 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lowe Boats FM 1625 SC 2021 with its 90-hp rating is the more economical daily driver.
