Hi guys,
I just bought a Hi-Max with a 447 up, and a B-box down.
Unfortunately, the previous owner has health issues and isn't able to converse.
Anyway, the gearbox has a threaded hole on each side about 1/2 way between the top and bottom of the gearbox.
I would surely think that these should be plugged, but I remember reading somewhere that they, or one of them should be open for cooling purposes?
Forgive me if this has been answered, but I couldn't find it. Newbie here
