Mercury 300HP XL FourStroke Outboard DTS

The Mercury 300HP XL FourStroke Outboard DTS puts digital throttle and shift control on the 25 inch X-long shaft in this 300 horsepower range. Controls DTS is an electronic throttle and shift system rather than a cable-operated remote, needing a compatible helm to run. Mercury also builds a cable-operated remote-mechanical version on this same shaft length, so confirm your helm wiring before treating this as a drop-in swap. Specifications Electric start and fuel injection are standard here, and the engine weighs 527 lbs dry. Power trim and tilt means running angle changes electrically, which is worth having on a V8 this size. Included and warranty Mercury tosses in a tool kit and mounting hardware alongside the manual, protected by a 3-year factory warranty. The propeller is not included; buy one on its own to suit your boat and typical load. Does XL-DTS fit the same mounts as plain XL? Yes, the shaft and mounting are the same; only the control system differs. Is a propeller included? No. Helm compatibility Before ordering DTS as a swap for an existing engine, confirm your current helm and wiring harness actually support Mercury's digital throttle and shift protocol, since older remote-mechanical consoles do not simply plug in without an upgrade. Budget time for that compatibility check before scheduling installation, especially on a boat that has previously run a different kind of control system.
