I have been tinkering on the SpeediFour as I have time. I have cleaned the points and carb. I have the lower unit off to clean out the old grease and check gears and bearings. So far all looks good. I will post some pic’s before I reassemble for those who may be interested.
Today’s question refers to the gearcase itself. On both the SpeediTwin and the SpeediFour, the cases appear to be identical on the outside. Gears may be different, and prop is different.
The case of the Four is missing the aluminum plug on the forward side of the gearcase, immediately in front of the propshaft. Is this plug necessary to keep water out, or is it cosmetic to make the case more streamlined.(HaHa, as if this case is streamlined to begin with.)
The attached picture is similar to mine, but mine do not have the extra wings. You can see the "Plug" area right below the water intake slots.

This is what my SpeediFour looks like.
And my Speeditwin. Love the greasefitting!
