oldbugs -> 7.5 outboard lower on 11cc (6/27/2012 2:51 PM)

 Will a K&B 7.5 lower fit on a K&B 11cc upper? I'm trying to find a 11cc lower but I can only find (not many at that) are 7.5 lowers. Thanks.

The exhaust port in the lower unit doesn't match the 11cc exhaust outlet. The 7.5 lower unit is tapped so the 7.5 can be bolted to the lower unit. The mounting holes on the 11 cc lower unit are drilled to allow 6-32 screws to screw into the 11cc case.

The short answer, "No, not without reworking a 7.5 lower unit.
