The previous owners of my boat replaced the original Port transmission, ZF HSW 800 VI, with an updated model, ZF 84 IV. For the first time recently I noticed a difference in the noise level between the two, the updated port one is much quieter when idling. I've always said the transmissions are louder than the engines at idle on all of my v drive boats, this transmission you can barely hear at idle.
