Looking for a 1984-2003 200hp Yamaha counter rotating lower unit. Will buy parts motor complete if price is right and lower unit is usable condition and this is easier for someone. Open to new/used/rebuilt. I have inquired to SEI for and aftermarket c/r unit, but am awaiting a response. My unit had a hairline crack for the last 5+ years even before I owned it and held oil, finally let go, no more prop, shaft, clutches, or gears. What a surprise planing off and both motors quit, tilt them up and see the bottom of one missing. Didn't hit anything, had 25' of water, just the sudden lock of the port motor put all the strain on the other and stalled it. Looks like my typical flounder season has already started, 4th year in a row. Even considering a regular rotation lower unit on this motor? Has anyone tried this ? Any ideas apprecated. Thanks.
