I recently acquired two 2002 Yamaha 150 hpdi motors with a 25" shaft length. Although I recognize that I can use a jackplate, I'd actually prefer to convert one engine to a 20" shaft by changing out the mid-section, drive shaft, and shift shaft.

I'd like to request help in identifying which other year/model Yamaha engines (parts) are compatible with the ones mentioned above in order that I can broaden my search, if possible, to include all possible options.

I'm also interested in asking what other swap parts, if any, in addition to the mid-section and two shafts will be required for the conversion--not including gaskets, seals, etc., of course.

I assume you're recommending that I cross-reference part numbers between different years/models to which use the same... That's works to a great extent, and I've done that. However, it's possible, I'm thinking, that there are mid-sections that "will work" from other models that use different part numbers, perhaps because of some inconsequential change (paint color, etc.).
