are twin 5.0l Bravo 3 motors big enough for a 310 sundancer?

I asked this question in regards to the 28' i was looking at with a single and i was wondering how the boat performs with 5.0l twins in a 11k plus dry boat that is a little bigger. Trying to figure this out, boating lol enjoyment and pressure

What year 310?

 

[keokie]

My boat is listed by Sea Ray as weighing 12,000 pounds. The 496's aren't any too much.

2015

The twin 5.0s with B3s will be plenty of power for that boat. I base this on my experience with a 280DA with the same propulsion you are considering and my current boat with 350 mags. Good luck.

they claim its 260 hp per engine, 5.0liter, which i dont see on the sea ray site

 

[ajcjr]

they claim its new mercruiser technology

5.0 260 hp isn't anything new. I know they downsized the boats, like the new 310 might be the old 280? If so the 5.0's will work fine

Engines V6 or V8?

I have the boat you are looking at with twin 5L (260hp) on Bravo 3, plenty of power. Top speed of 42 MPH. At 3500 will go at 27mph, at 3700 I think a little above 30. With a clean bottom she gets aprox 1.4 mpg, and about 19-20 gallons per hour. If you can afford it get the Axius. Good all around boat

Enjoy,
Dave

Engines V6 or V8?

Small V-8

I have the 05 280 which is essentially the same class and size as the 2015. My 5.0"s push the boat fine. And the fuel economy is good.
