The Glastron GTDW 205 SURF 2021 vs Glastron GX 255 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.

The Glastron GX 255 2006 tops out at 375 hp. Engine specs for the Glastron GTDW 205 SURF 2021 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Glastron GX 255 2006 is rated for 7 passengers, while the Glastron GTDW 205 SURF 2021 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Glastron GX 255 2006 could be the deciding factor.
