When two boats share the same hull type — in this case both the Stamas 270 Tarpon Inboard 2006 and the Stamas 310 Express Outboard 2010 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?

The Stamas 310 Express Outboard 2010 tops out at 500 hp. Engine specs for the Stamas 270 Tarpon Inboard 2006 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Stamas 310 Express Outboard 2010 is rated for 9 passengers, while the Stamas 270 Tarpon Inboard 2006 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 310 Express Outboard 2010 could be the deciding factor.
