production motors..............
99% of tha time 2 liter motors were 2 ta 1's standard.. 2.4's were 1:87's standard ('cept xr4's)…
forgot!!! need ta "qualify" that statement... its merc so nothin' "is written in stone"...…..

135 and 150 were 2.0 and 2:1, 175 and 200 were 2.4 and 1.87. Exception was the XR4 which was 2.4 150 and 1.78:1 small gearcase. AFAIK anyways.
As with everything Merc there are always exceptions and they used what they had. If they needed to ship a 2.4 and were out of 1.87’s they would have just slapped a 2:1 on it and sent it out the door!Josh Peterson
