Looks similar to the one we sea trialed, it had twin gens. Deceiving when you look at the center line distance on the engines compared to the stern pic in the yard. They could have went outboard a bit more with the engines. Unless you want a fast cruise those 3406E's are a good engine for that boat if speed is not an issue. Seems we saw around 16 kts cruise, but had a trim tab stuck in down position, which bombed out the sea triaI. Boat was really light on fuel, water, and equipment. No tender . Think the later models went to the C18"s for a faster cruise, but still great inline engines for more room in the ER. They may have kept the engines tighter because of exhaust getting into the tunnels. The underwater exhaust ports are outboard and forward of the tunnels, one of the outlets on each side of transom are probably low rpm exhaust ports, the other two could be for the gens.
