- Easy bolt-in installation; serviceable without drydocking
- Replaceable propeller blade bearing liners
- Several propeller blade materials and designs; CP and FP propeller options
- Multiple seal system with Environmentally Acceptable Lubricants (EAL) only at the outer oil-to-sea barriers, reducing the EAL quantity required
- US EPA Vessel General Permit (VGP) compliant
