Product Description:

Unique, problem solving product for special situations:

JackPlates are for lifting the engine, raising the propulsion and prop level, but Dropdown Plate is for lowering the engine height by dropping down the outboard in the water if required.

  • Unique, but standard size manual DD Plate from 40Hp to 150Hp, or for maximum 250kg outboard engines
  • Two-piece, lightweight, but strong and cost-effective design with adjustable stainless steel screws on both parts for lowering the engine side and outboard engine
  • MADE IN USA: Made of high strength polished 10mm thick Aircraft Quality Aluminium Alloy
  • Basic RAW aluminium surface, but optionally hard black, or clear anodizing surface for saltwater or brack water usage protecting the hardware against natural corrosion
  • 6 inch setback, meaning 15,24cm transom-engine ofset, longitudal  DropDown Plate size
  • Standard product for mounting bolted motors on BIA standard hole pattern, even interchangeably regardless of any engine brand
  • Factory pre-drilled standard BIA hole patterns (327mm on the top, 237mm on the bottom, 203mm vertical spacing)  on both sides of the product
  • Three different BIA hole pattern setting on both side allows the installation on the transom on the good height and lowering the engine to the required deep
  • 3 inch, meaning 7,62cm basic lowering direction, basic negative height difference between the transom and engine side
  • Possibility to drop the height 3,5 inches, 8,89cm in parallel, through the screws on both sides of the structure for lowering the outboard engine
  • Alltogether 6,50inch, so 16,50cm possible outboard engine height lowering
  • Lightweight, but strong construction with a total weight of 9.50 kg, Special product for cost-effective mounting of smaller and middle ranged outboard engines


It is VERY IMPORTANT to make sure that due to  lowering of the engine, there is enough space left for the engine tilt, trim, cables, steering rod, or even the steering arm or  for the fuel system.
