When two boats share the same hull type — in this case both the Stamas 270 Express Outboard 2010 and the Stamas 290 Tarpon Outboard 2011 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?

On paper these two are close siblings in the size department — Stamas 270 Express Outboard 2010 at 28,8 ft versus Stamas 290 Tarpon Outboard 2011 at 31,6 ft. At 58 lbs and 6 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 Stamas 270 Express Outboard 2010 carries a rated maximum of 450 hp.
