Can anyone tell me if the engine points straight ahead or is it off a few degrees ?
If so will there be a difference for the 180 hp ??

Re: Engine Thrust Line
I don't have the details available to me here in DFW, but the engine does not "point straight ahead". You were probably just referring to longitudinally/laterally, but I am thinking (if I remember correctly) that the engine thrust line is displaced vertically.
I'll try to see if I can locate any data on it this next week.
I do not know about the 180 hp conversions.
