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

I'm confused -

 

it is normal to use stainless bolts to secure anodes (aluminium or zinc) to steel; do I take it your trim tabs are aluminium (which would make sense re the bolts but less with regard to the anodes unsure.gif )

Fairy normal to fit hull anodes with mild steel fixings , but Stainless ones are available.

 

All the shaft anodes I have used, have had stainless machine screws.

 

The ones on my volvo leg are a right mixture, ohmy.gif 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. dry.gif

i dont pretend to understand the details but the boat yard told me to use aluminium because that was what the anodes on the drive were made from- and they are presumably (looking at their placing and shapes) tailor made by Yamaha for the leg

yes - aluminium anodes fine on Merc B3 and Yamaha drives

 

I was just questioning why you thought it wrong to have them fitted with stainless bolts.

 

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.
