Hi Annie,

Have used Aluminium on both our boats and they have been fantastic for both Burgh Castle and Reedham.

We only use Performance Metals anodes that are specially formulated for the aluminium of the particular drive. You can buy cheap ones but I wouldn't risk it, you may well find that the anodes on the boat Baz refers to were sourced from the local car boot for £5 each.

Performance metals claim a life 3 times that of zinc in Salt and 5 times the life of Magnesium in Brackish/fresh, I have seen nothing to make me question this and they are always part worn. As long as the anode is more reactive than the drive it will protect, if they can make them slightly more reactive then they will protect for longer.

Magnesium in salt will be gone in a couple of weeks.

Hi

Just to say I have magnesium anodes on Osprey and they have been on for 2 years in two weeks time and thats two winters in the water and 9 days over that time in the sea, two weekends and 2 day trips.

my anodes are around half way worn on the trim tabs and bars along the stern so they are working but last a little longer than 2 weeks sea use i think

Yours are also a little bigger than those found on Stern Drives Baz, remember on a stern drive you will have a ring anode and a small bar anode, if they were magnesium in salt you could watch them disappear.

yes your right there as on my old boat with 290 stern drives, the anodes would last no more than 2 years at Acle on the northern broads.

Do you think mine with last enough for the london trip?

Depends how big they are Baz, if they are anything like the engine oil and filters they should have a 5 year service life
