I recently purchased a 1983 boat that had a late 1960's KIEKHAEFER CORP. MERCURY 950 95 HP SIX with a model No. 2212108. The only date stamp that I was able to find on it was a date of 1967 on the distributor body. It is a complete running motor in very good condition with throttle and ignition in same housing, along with mechanical and push button choke as part of the throttle quadrant. I've been told recently that this may have been a limited production model between the times of engines able to start in gear to those that were federally mandated to only start in nuetral. I also was told that it had a nickname of " the tower of power " or " the 95hp tower of power " and is a sought after engine as a " nucklehead would be to a Harley collector. I would appreciate any feedback about this engine and would be interested in owners manuals and or shop manuals for it as well. Thankyou for your assistance. Reed
