Details & Inspection Notes

The Mercury 300HP L FourStroke Outboard DTS pairs the 20 inch shaft, the shortest in this 300 horsepower range, with digital throttle and shift control instead of a mechanical remote.

Controls

DTS gives electronic rather than cable-operated throttle and shift, needing a matching DTS helm to run; this differs from the remote-mechanical version Mercury also builds on the same 20 inch shaft length, so confirm which control setup your boat already carries before ordering a replacement engine.

Specifications

Electronic fuel injection and electric start come standard on this V8, which weighs 527 lbs without fluids. Power trim and tilt is fitted too, so running angle adjusts electrically rather than by muscle, worth having on a motor this size.

Included and coverage

What's in the crate: mounting bolts, a tool kit, and the owner's paperwork, protected by Mercury's 3-year factory coverage. Buy the propeller separately, sized and pitched for your boat rather than assumed.

Who runs DTS

Digital throttle and shift tends to show up on boats already wired for electronic controls from the factory, or on repowers where the owner is upgrading the whole console alongside the engine.

Can I switch this to remote mechanical steering later? Not without re-rigging the helm; DTS and remote mechanical systems use different hardware. Is the propeller included? No. Is a DTS helm included with this engine? No, the helm and wiring are sold separately and must match Mercury's DTS protocol.
