Exhaust Elbow
The exhaust elbow on all wet exhaust engines is subjected to heat and salt water and is consequently very prone to corrosion. Initially Nanni used an aluminium casting with no provision for an anode. More recently an anode has been fitted but the inlet spigot still corroded very quickly. In at least one case, in less than two years. The latest design (2012 model see picture) has a brass(?) inlet spigot which hopefully will last longer. Also in the picture is the exhaust elbow gasket and anode. The anode has a copper washer not shown in the photo.
Keep an eye on your exhaust elbow. It is easy to remove and you should check it at least every two years.
When removing the anode use a well fitting hex socket. (Not the type that only connects on corners). Considerable force may be required to remove the anode and it is easy to round off the corners of the carrier bolt so that the anode is no longer removable.
It may even be advisable to remove the anode every six months just to check it is removable.
