Mercury 350 Ocean Runner PVC (Grey) 2007 vs Mercury DR400 2008 — Same Brand, Different Boat

The Mercury 350 Ocean Runner PVC (Grey) 2007 vs Mercury DR400 2008 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 — Mercury 350 Ocean Runner PVC (Grey) 2007 at 11,0 ft versus Mercury DR400 2008 at 13,0 ft. Weight tells a clearer story for trailering families: the Mercury DR400 2008 tips the scales at 313 lbs — 295 lbs less than the Mercury 350 Ocean Runner PVC (Grey) 2007 at 18 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 25 hp for the Mercury 350 Ocean Runner PVC (Grey) 2007 and 40 hp for the Mercury DR400 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.

For family outings this is probably the sharpest distinction between the two. The Mercury DR400 2008 is rated for 6 passengers, while the Mercury 350 Ocean Runner PVC (Grey) 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury DR400 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 350 Ocean Runner PVC (Grey) 2007 comes in at 1 lbs per hp versus 8 lbs per hp for the Mercury DR400 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Mercury DR400 2008 if your priority is putting more people on the water — it handles 6 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Mercury 350 Ocean Runner PVC (Grey) 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Mercury 350 Ocean Runner PVC (Grey) 2007 vs Mercury DR400 2008 — Common Questions

Which is the larger boat — the Mercury 350 Ocean Runner PVC (Grey) 2007 or the Mercury DR400 2008?
The Mercury DR400 2008 is the longer of the two at 13,0 feet overall. The Mercury 350 Ocean Runner PVC (Grey) 2007 comes in at 11,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Mercury 350 Ocean Runner PVC (Grey) 2007 or the Mercury DR400 2008?
For trailering, the Mercury 350 Ocean Runner PVC (Grey) 2007 has the edge at 18 lbs dry weight versus 313 lbs for the Mercury DR400 2008. 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.
Which boat can handle a bigger outboard?
The Mercury DR400 2008 is rated to a maximum of 40 hp, giving it the larger power ceiling. The Mercury 350 Ocean Runner PVC (Grey) 2007 tops out at 25 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Mercury 350 Ocean Runner PVC (Grey) 2007 is Coast Guard rated for 5 passengers, while the Mercury DR400 2008 is certified for 6. 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.
Which boat has the better power-to-weight ratio?
The Mercury 350 Ocean Runner PVC (Grey) 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 8 lbs per hp for the Mercury DR400 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Are the Mercury 350 Ocean Runner PVC (Grey) 2007 and Mercury DR400 2008 from the same manufacturer?
Yes — both the Mercury 350 Ocean Runner PVC (Grey) 2007 and the Mercury DR400 2008 are built by Mercury. 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.
