help needed for my m8ts 150 hp its from the 1973 some years round there the last 2 no,s in the serial no is 99 , any info would be appreciated , many thaks
Not sure I can verify the year from that info. Normally those inline sixes used Champion L-76V or L-78V. A Champion application chart will narrow it down further, if you can decide on the year. My '77 Merc 1500 called for Champ L-76V or NGK BUHW. Of course the '77 was slightly different in design.
