Nanni Zinc

[noelex 77]

Be aware Nanni have changed the manufacture of their exhaust elbow from the original cast iron to aluminium. (at least they have on my 15hp 2.50HE)
With this change they have incorporated a zinc (which need regular changing) into the elbow.
The zinc is not mentioned in the handbook (because the zinc is new) and owners of Nanni motors may be unaware of the need to check this.
