Does anyone have experience with this engine? I'm looking at a boat that has this engine. It's a big beast, much larger than other engines I've had with similar specs. This is a 1800rpm engine the produces 660hp. Above 1500rpm it starts to move. At 1800 rpm it's moving a lot. Some have told me that this is because of the mass of this type of engine. That doesn't seem right to me... Below 1500rpm it's smooth. To me, this feels like an alignment, shaft of prop issue. Thoughts?
