The new Mercury 300XL SeaPro Commercial AMS targets jobs like patrol and rescue work, where an outboard runs long hours without much of a break. This 300 hp V8 pairs digital throttle and shift with electro-hydraulic power steering as standard gear, on a 25-inch shaft and an advanced mid-section meant to isolate vibration from the hull. Coverage built for continuous duty Mercury's commercial-only terms on this unit allow unlimited hours of running within a 2-year limited standard warranty, reflecting the heavier use these SeaPro motors absorb compared with recreational ones. The 4.6-liter, 279 cid V8 peaks at 4800-5600 rpm, a torque-focused tune rather than a high-rpm one. What comes fitted instead of optional Digital throttle and shift plus electro-hydraulic steering arrive ready to run on this AMS trim rather than as separate add-ons, which is the main difference from the base SeaPro. That extra hardware draws more current, so Mercury fits an 85-amp alternator, and dry weight for this trim comes in at 527 lbs. Is the power steering included or an add-on here? It is built into this AMS trim, not a separate purchase. What does the warranty actually cover? Unlimited hours of operation within a 2-year limited standard warranty, written for commercial operators. Since it ships new and is aimed at fleet or agency work, check your mounting and control wiring against this AMS configuration, since the base SeaPro trim is wired differently.
