The Princecraft 20 ST 2004 has the bigger tank at 34 gallons, versus 6 gallons on the Princecraft Platinum SP 186 2004. That 28-gallon difference translates to roughly 84–140 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Detailed Evaluation & Buyer Recommendation

Princecraft 20 ST 2004 vs Princecraft Platinum SP 186 2004 — Same Brand, Different Boat

The Princecraft 20 ST 2004 vs Princecraft Platinum SP 186 2004 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 Princecraft Platinum SP 186 2004 tops out at 175 hp. Engine specs for the Princecraft 20 ST 2004 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Princecraft 20 ST 2004 carries 34 gallons versus 6 gallons in the Princecraft Platinum SP 186 2004. 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 Princecraft 20 ST 2004 is rated for 13 passengers, while the Princecraft Platinum SP 186 2004 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft 20 ST 2004 could be the deciding factor.

Bottom line: Choose the Princecraft 20 ST 2004 if your priority is putting more people on the water — it handles 13 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Princecraft Platinum SP 186 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
