Yamaha SR230 2005 vs Yamaha SX230 2006 — Same Brand, Different Boat

The Yamaha SR230 2005 vs Yamaha SX230 2006 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.

On paper these two are close siblings in the size department — Yamaha SR230 2005 at 23,0 ft versus Yamaha SX230 2006 at 23,0 ft. At 29 lbs and 3 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 — 280 hp for the Yamaha SR230 2005 and 280 hp for the Yamaha SX230 2006. 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. Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.

Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Yamaha SR230 2005 and Yamaha SX230 2006 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Yamaha SR230 2005 vs Yamaha SX230 2006 — Common Questions

Which is the larger boat — the Yamaha SR230 2005 or the Yamaha SX230 2006?
The Yamaha SX230 2006 is the longer of the two at 23,0 feet overall. The Yamaha SR230 2005 comes in at 23,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Yamaha SR230 2005 or the Yamaha SX230 2006?
For trailering, the Yamaha SX230 2006 has the edge at 3 lbs dry weight versus 29 lbs for the Yamaha SR230 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Yamaha SR230 2005 is Coast Guard rated for 1 passengers, while the Yamaha SX230 2006 is certified for 1. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Yamaha SR230 2005 and Yamaha SX230 2006 share an 8 ft. 6 in. (2.6 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Yamaha SR230 2005 and Yamaha SX230 2006?
Both boats carry similar fuel loads — 5 gallons and 5 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Yamaha SR230 2005 and Yamaha SX230 2006 from the same manufacturer?
Yes — both the Yamaha SR230 2005 and the Yamaha SX230 2006 are built by Yamaha. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
