The run drawn here is the 3 m reference run sized below. Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. Confirm your own run length, routing and terminations before ordering — open this part in the designer to size it against your actual system.

What size cable and fuse does the MD2020 19HP need?

Cranking current110 A12 V system

Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The cranking current is the starter's continuous draw. ABYC E-11 excepts cranking-motor conductors from overcurrent protection, so the fuse shown is the conventional cranking-rated (Class T) choice sized to hold the draw without nuisance tripping — not a wire-protection requirement. The conductor is sized by the Crimp engine for the cranking draw and voltage drop. The 3 m one-way run is a stated reference, not a universal installation prescription.

What else you need to wire the MD2020 19HP

  • 6 m total of 95 mm² (3/0 AWG) marine cable
  • Four 95 mm² cable lugs matched to the equipment studs
  • 250 A cranking-rated (Class T) fuse at the battery
  • Heat-shrink, strain relief, and terminal boots sized to the cable

Catalog profile

The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.

Engine reference

Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
