I'm currently looking to purchase a boat with this engine. I know Volvo engines are typically more expensive for routine maintenance. This engine only has about 350 hours on it. I'm curious about any pros and cons about this motor. At WOT it spins at 2200 rpm and 25 knots. At cruise of 20 knots it's at 1800 rpm and about 1.1 mpg. Thank you for any input!
