b376756 would be 0B376756 which is a first gen 2.0 175hp.

Others are not showing up as valid serial numbers. Not all those early ones were recorded though, so my guess based on what I have seen is mid eighty's or earlier 2.0s and 2.4s

Oh boy

**boatermike** · 05-16-2021, 02:16 PM

yes i agree what a mess, only one way out is to bet busy and turn them wrench's. one of these is going to run

Any chance the white one is a 1988 Sea Ray 135??? These were installed on Sea Ray 18 foot outboards, the first year they were white on the outside and black on the inside and said Sea Ray in little print, 1989 they were Mariner gray and still called Sea Ray and 1990 on they were just black Mercs.

...they were also rigged onto all their center-console boats of all lengths as both single and twin installations...(the 135's)...

...really hard to tell from this photo, but the red flywheel motor in the forefront with the aerosol can on top, is a 1976 thru 1979 motor, due to the old style clamp bracket. the other motor hard to say but could be the same. the red flywheel motor upside down in the very back, might have water in the cylinders due to being tipped so far upside down...

...1984 & up oil injected 135/150/175...

**FUJIMO** · 05-16-2021, 02:55 PM

...1976/77/78 175 or 150??? (old style clamp bracket?)

**boatermike** · 05-16-2021, 03:00 PM

the white one has the b serial number and the back cowl bracket says 175
its the only one identified so far
the one hanging on the boat is supposedly a 1978 and the one ripped apart is also claimed to be 1978 but im questionable on the guys words. i bought them through a person here.......
need to identify the best one and rebuild it.
