Ok, in addition to quering Frank A...who has shown to be pretty versant on the force front for sure, I would like to put a quick couple of questions to anyone else in the 'know'.
Did the Force 90hp's come with both a single and a 2 piece driveshaft in the 20" Lower Unit configurations? (the years I am particularly interested in are the 90'/91's). Or...were/are they all 2 piece driveshafts? Now, as well....would the lower unit housing be common to either single or 2 piece driveshafts...if indeed these were both available?
The reason I ask is that I have a line on a complete lower unit (w/ housing) that may help me fix that '91' winter project, however it is supposedly a 2 piece system and I have not taken my existing one apart yet to know if it too is a 2 piece...or even if it matter to the housing. It looks identical...but its best to get as much info before hand as possible on this kind of stuff I find.
Any feedback on this would be appreciated and of course many thanks!!!

Not totally sure on this, but I think 90/91 they went to a 2 piece. I know 88 was a one piece (that I managed to make into 2 worthless pieces!)
But the LU styles are diferent animals, no interchange
