1976 115 lower unit interchange with 1990 90

[mspring]

Will a 1990 90 horse lower unit interchange with a 1976 115 - Johnsons of course?

seriously doubt it, the 76 is a hydro mechanical lower unit, the 90 is a mechanical lower unit.

Just about nothing on a 1976 115 HP motor will work after 1977. Have you tried Horne's Marine Salvage in St Petersburg? salvagemarine .com 727-896-1032

They will not bolt up. We could get around the type of shift issue but those two motors have different bolt patterns.

We'll assume you need a lower for a 1976 motor. You'll need a lower from any 1973 to 1976 V4 or a lower from a 1977 20" 85 or 115. A lower from a 1977 140 will not work either.

And, DHadley implied this, but I'll state it explicitly. The '77 XL shaft (25") won't work either.

I'm assuming that he is still talking about the same motor as in his earlier threads. http://forums.iboats.com/showthread.php?t=235138
