Im trying to find what size bolts mount the lower unit to the upper half on a 1973 25 HP. 25R73A is the model. Also is there a forum with helpful diagrams anywhere? Ive had a hard time finding much of anything for this old outboard.
 
Exploded parts diagrams are right here (free) at marineengine. Service manuals are here also at a fair price. I couldn't tell you the bolt size without removing one and looking. But needless to say you could do that yourself.

That isn't an "old" motor in some people's eyes. You need to discover the Antique Outboard Club and their website www.aomci.org
