I have a broken driveshaft snapped off in the pinion bearing in the lower unit on my OMC 800 . I have a known good OMC 400 unit , includes everything from the bellhousing to the prop.

So far my research has shown that the drive shaft, prop shaft, and gear ratio are different . Can I run this on my V8 boat, maybe change the prop pitch to compensate, and keep on boating ? If anyone wants to trade a 800 for a 400 let me know too! : )
