When two boats share the same hull type — in this case both the Starcraft Marine 1700 IO Fish 2008 and the Starcraft Marine Star Step 190 IO 2008 are modified vee designs with fiberglass construction — 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?

Size is the most obvious dividing line here. The Starcraft Marine Star Step 190 IO 2008 measures 21,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Starcraft Marine 1700 IO Fish 2008 at 16,0 feet (2008). At 155 lbs and 225 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.

Both boats share a closely matched power ceiling — 4 hp for the Starcraft Marine 1700 IO Fish 2008 and 4 hp for the Starcraft Marine Star Step 190 IO 2008. 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. Fuel capacity breaks the other way: the Starcraft Marine Star Step 190 IO 2008 carries 51 gallons versus 23 gallons in the Starcraft Marine 1700 IO Fish 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Star Step 190 IO 2008 is rated for 10 passengers, while the Starcraft Marine 1700 IO Fish 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Star Step 190 IO 2008 could be the deciding factor.
