Re: Anodes/Zincs for Volvo
Ok, took some digging, but found the answer. Your drive was converted to a DP by someone, someplace along the line. The lower unit is from an early 96 NC model. First year for the DP-S drives and only the early models of 96 had the side plug. That is the only time they used the drain plug on the outside. After that (Late 96,97 and on), it was behind the prop.
Guess I never seen one of the originals, went to DP-S school in 97 and they didn't say anything about it.
