NOTE: Above drawing entry for bushing & QDs includes a quantity of 4 which is applicable to 225 WLB Class where there are two thrusters (Bow & Stern). Not so for 175 WLM Class where there is only one thruster (Bow). So, quantities noted above should be changed from “4” to “2” for both bushings and QDs.

Since thrusters on 225 WLBs and 175 WLM classes are the same, material requirements are the same.
