I just bought a M-40 E Mariner outboard. # 6E9 S 102837 what year is this please? Also does this motor charge the battery while running if it has electric start? Thank you. Bob O
Between 1982 and 1984... Mariners were not sold by year model, but by 'features'.. Yours is probably closer to 1984 than anything else... Yes, it should charge the battery.....
