The '81 OMC Saildrive in my 'new' (acquired in June 2010) '81 7.3 runs like a charm. 2011 was the first season in the water for boat and motor and I was very pleased with the performance of both. However, I noticed the lower drive unit is slightly angled off to starboard and does not line up directly 'in line' with the keel and rudder. After reviewing OMC's mounting and installation instructions for the Saildrive, I don't see any obvious adjustment to be made since the holes on the mounting flange of the motor line up with the holes on the mounting flange that is glassed in to the hull to mount the motor. I guess that means also that the whole motor is slighly askew. Was this an error in initial installation or am I missing something obvious and the problem might be easily fixed?
