Boattest.com has reviews of the Mercury at: http://www.boattest.com/engine-review/M .. 2-MAG_2013![Cobalt Cobalt](https://upload.wikimedia.org/wikipedia/commons/6/67/CoA5Br_Br2.png)
and the Volvo at: http://www.boattest.com/engine-review/V .. 8-430_2013
After comparing the two, the Mercury is an 8.2 liter that weighs 1122lbs without the lower drive, and puts out 380 or 430 HP depending on configuration. The Volvo is a 6.0 liter block (replacing their own previous 8.1 liter block) that weighs 1115 with the stern drive, and puts out 380hp or 430hp depending on configuration.
The Volvo includes variable valve timing, and both engines bring a 6000 lb boat to plane in about the same time, and max out around 3mpg running at about 30mph. Both are modern designs with service components located near the top, and include options such as salt water stern drives and a variety of controls including digital and joystick controls.
