Bulletin No. SB-804 Stern Brackets
SUBJECT: Modified stern bracket Nos. 307281-port, and 307282-starboard. 1960 - 75 H.P. models V4S and V4SL-12.
Pictured are both the old and new style stern brackets for the 1960-V75 series engines. Note the reinforcement changes at the points indicated by arrows in figure 1. Note also that the new style brackets can be further identified by the cast letter "N" on bracket 307281-port, and cast letter "H" on bracket 307282-starboard.
Whenever either stern bracket requires replacement on any 1960 V-75 which has the old style parts, figure 2, it is strongly recommended that both old style brackets ALWAYS be replaced with a pair of new style units to insure equal support on both port and starboard sides of the engine. NEVER INSTALL ONE NEW STYLE BRACKET WITH ONE OLD STYLE UNIT.
