BMAX4iii leaky diff outdrives

[andrewc]

Hi all

As title, a little diff oil seeping out I think via outdrives.

Having read a little it seems the kit o rings which are black can be replaced with orange ones which are more effective?

There's also a note in the manual about adding the 'supplied' o rings to the outer side of outdrive; it's in the exploded diagram of diff on page 5 of manual here:

Can anyone give me a part number for these o-rings please? Got the part numbers for black and orange inner rings, but nothing for outer ones?
