Both the Jetcraft 1975 Fastwater 2012 and the Jetcraft 2025 Discovery HT 2012 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

At 1 830 lbs and 1 850 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Jetcraft 2025 Discovery HT 2012 tops out at 225 hp. Engine specs for the Jetcraft 1975 Fastwater 2012 aren't listed - confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads - 45 gal and 45 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Jetcraft 2025 Discovery HT 2012 is rated for 6 passengers, while the Jetcraft 1975 Fastwater 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jetcraft 2025 Discovery HT 2012 could be the deciding factor.
Bottom line: Choose the Jetcraft 2025 Discovery HT 2012 if your priority is putting more people on the water - it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably.
