Silent Six Ser. # 1186675.wat er pump out, ive taken the lu off and removed the two pin hole cover, the water pump is not there and cannot be there, sooo i got some help where cylmer book shows removing one cross pin and one centering screw in the cover that covers most of the vertical shaft or drive line. instruction say pull down on this cover to uncover water pump. boy this thing won't move at all, i've loosened the shift cable and the mounting screws for the powerhead, the powerhead will not move up and this cover will not move down. any idea? would like to meet someone who has worked on a silent six. anybody with diagrams as well. thanks
