Fitment & Ordering

Match actuator part number 303974 to your equipment model, serial information, mounting dimensions, electrical connections and required stroke. Existing information states both that standard systems can be retrofitted to high-speed operation and that this actuator is not for standard, non-high-speed jack plates. Confirm the approved conversion procedure and required components with the manufacturer before ordering; do not treat it as a direct replacement for every standard system. Verify package contents, operating limits and permitted water exposure. Seal construction does not guarantee leak-free operation or unrestricted submersibility. Have installation and compatibility checked by a qualified marine technician following the manufacturer's instructions. Contact C and O Marine Parts with your equipment details for help confirming the correct actuator.
