I will post some pics. Assuming it’s a ’69, the specified impeller housing is a 313543. What was in the motor was a 303070. The difference appears (I’ve not had the two in my hands to compare directly) to be that the 313543 has shorter "fins" in the drive shaft opening so the spacer can spigot in. This would account for the mickey-mousing of the spacer. Interesting is that if you do a search for 313543, and look a the pics of what people are offering on ebay, many of they are actually 303070. This, for example: http://www.ebay.com/itm/Johnson-Evinrud … 14&vxp=mtr
If this is so, I have a 303070 in decent shape and it might be converted by chucking it in a lathe and trimming the fins, or even just doing it with a dremel or die grinder. i think this is what Fleetwin was saying earlier?
On the other hand, I’m still noticing the four screw holes. Maybe it was machined to take either the metal or plastic pump? Could investigate this on the net until eyeballs fry without resolving it 100%.
