Hi guys, thanks for the kind words. Main power is a single Volvo D6-370HP diesel. At 3000rpm she runs 30mph and burns 13gph diesel. DPH-D outdrive. 16,000 pounds displacement. Tim - Sold the 306 Grady to a local so you'll still see 'Weapon' around but I'm not running it anymore. That was a great boat - a soft and dry riding hull.
