I'm considering switching to aluminum engine pencil anodes.
6 months is about the max I can go. Wear rate seems unrelated to engine hours and the zincs most affected seem to be the ones that sit in raw water when the boat is not in use.
After 6 months a few of them will likely break off and lead to pulling off hoses and searching for pieces.
So considering cored aluminum anodes from Performance metals.
I have twin Cat 3208 NAs with 5 zincs on each engine.
I am in salt water 100% of the time.
Does 6 months sound like a short period of time for engine zinc wear especially if it's during my off season when the boat sits more?
Right now I have zinc anodes on the shafts/rudders/transom and everything is bonded. From reading, sounds like the aluminum anodes in the engines might protect the zinc anodes in the outside water and wind up depleting faster.
Anyone out there have experience with zinc on the outside of the boat and aluminum in the engines?
Thanks
