ospreyman Posted February 18, 2012 Report Posted February 18, 2012 Stainless in Aluminium ? found out yesterday afternoon that the yard had not done my trim tab anodes as requested. grabbed new before the shop shut and went to do them this morning, stainless bolts into aluminum anodes which had corroded solid - to the point that you could not get the allen key in! half an hour to find some electrikery then half an hour upside down with angle grinder, safety glasses misted up, in wind and rain down the back of the neck to get the old ones off, 2 mins to get the new on, cut em off and replace. boats who would have em! good luck and hope it goes better than the above Quote

All the shaft anodes I have used, have had stainless machine screws. The ones on my volvo leg are a right mixture, they use stainless bolts passing throgh the moulded zinc anode [which probably has a stainless plate moulded inside] these bolts then go into the Alluminium sterndrive unit. Just add salt water [hard not to when afloat most of the year] and this combination ensures that the sacrificial anodes need replacing often, I wonder if that is why they are made this way.

However, re-reading your post it's possible you were just making the observation that you had had to cut your old ones off before installing new ones - presumably with stainless bolts/fittings. If this is the case then miss read your post and apologise for the confusion; which was just mine. I see Charlie has posted effectively the same thing. Quote
