Propeller Shaft Anodes

Postby carl » Wed Feb 08, 2017 12:38 pm

Question:
Do any of you Marinette owners use anodes on your propeller shafts? And if you do what type?

Nothing wrong with putting anode shaft collars on them. The problem is finding the correct type. Marinas normally only have zinc which does nothing. Your Rudder,Keel and tab anodes if properly maintained will be sufficient.

Aluminum is the proper one to use. Mag. is too hot and they will not last long and are too hot for salt or brackish water.

I have used the exact anode from Barkley Dave's link for the last 3 years. My engine is isolated from the shaft with a Globe Drivesaver, but the anode is on there for peace of mind.

I use the shaft anodes from BoatZincs as well. Always a good idea in my mind.

Marstro,
Thank you for mentioning the Globe Drivesaver, I had to Google search it and these couplings are a good match for our Marinette boats considering the need to isolate our shafts. Thank you for sharing. Awesome product. Find it here: https://www.gcsmarine.com/content/drive ... rivesavers

I used Boat Zinc on mine and they needed replacement every two years (in brackish water). That means they were working, right?

That is why they are called "sacrificial" anodes. Better to have them get eaten up or dissolved than the boat.
I put new shaft anodes on every year. It is hard to find the aluminum ones. Different brand names for the aluminum anodes but they are all the same alloy. Best place to go is boatZincs.com You could call them up and tell them you have Marinette, what size it is and they will know exactly what you need, and have the best price.
If you are shopping for Globe Drivesavers, be sure to shop around. Prices vary wildly by who sells them. All made by the same company. Found some companies marking the price up 3 or 4 times the cheaper places. Easy to save $600 to $800 if you shop around.--Ed
