Looks like your 8 ML serial number is within serial number range 677-352106 - 677-367080 which makes it an 1981 engine year.Hi Graham, I too have just acquired an old motor, Mariner 8 serial 677 352170
I purchased an old Coronet 20 Trailer-sailer as a restoration project and the motor came along with the deal.
I cannot find any suitable owner manual online and want to take the top cover off, check and change as necessary plugs, filters etc. but cannot take the cover off.
I have managed to unclip the cover at the throttle end but thought that it would come off from the prop end to get past the pull start handle. ? Don't want to force and I know I'll get there but maybe you can direct me to where I can find the appropriate owner/ tech manual ?
Any help is appreciated, in advance.

The model number that pops up (7008208) while running the serial number shows this one to be a 1978 engine year.Can anyone help with the model year of my 8hp mariner? 8m 677 s052553
Thanks in advance.

The OEM service manual part number would be 90-14679 that fits 8B (677)/W8 (677)/Marathon 8 (677) 9.9C (682)/15C (684)
(I) All serial number ranges.
