Re: Concerned about owning a Volvo...
I believe the Mercruiser and Volvo to be the same, and in some respects of accessories to be Superior. I've worked on used boats for about 6 years mainly 2000 and older, I've seen some new mercruisers and my nephew owns an 08 VP with a 5.0 and I love everything about it, from the Carb selection, to the intake manifold, Exhaust design, water drain and expecially the Oil Filter placement and ease of Re-placement.
The mercruiser carb 5.0 uses a low-rise intake where the 5.0 VP uses a High Rise intake manifold giving it more top end power. ( i think )
