That’s not calcium, it is what is left of a badly depleted anode - need to replace it ASAP.

 

Where are all the anodes on a 2000 Searay 240 Sundancer

 

I assume there is one for each trim tab and is there one for the outdrive unit

 

One on each trim tab. See mine top of picture, one on each trim cylinder, 2 you cant see on front of outdrive, and some have 1 behind the prop. Aint she pretty! That is a 30yo Bravo 1 after $2k of reconditioning and upgrading all internal and thru transom accoutrements.

Roger,

You will need two round ones for the trim tabs. They come as a pair. If you have a stainless prop (Common on some Bravo 2) then buy two pair and make a trim tab sandwich. If you have aluminum, you only need one on the top side.

Go to Boatzincs.com they are the best online supplier for anodes. For the age and type of your drive, they will have a kit of all the parts you will need. The Bravo has several, two trim ram, one, or possibly two on the underside of the cavitation plate, and one up front of the lower unit. You ight also give your Mercathode a clean.

What anode metal you need depends on where you boat, salt, brackish, warm, cold etc.

 

Thanks everyone, I placed an order with Boatzincs.com for the Bravo 2 anodes and for the two trim tabs.

 

how do you install them on the outdrive steering pistons if they have never been installed. I can't find any instruction on where to drill or install the screws (zincs at the bottom of this pic

 

When I bought the kits for mine, it came with those anodes. My drives don't have them installed as well as the one behind the prop. I just left them off. I was afeard of drilling and tapping the screw holes and having to buy new ram ends.

 

To answer your question about how to clean up the mess, use HCL. It is sold under various brand names, Zing being one of the more common ones. Wear old clothes and have a hose with fresh water near by. Follow the directions.

 

The generic term for an HCL/water blend is Muriatic Acid. You can get it in different percentages ranging from around 15 to 30%; check the labels. Possibly the most important thing to remember about any HCL-based formula is to keep it away from chlorine bleach, as it'll release nasty amounts of chlorine, possibly lethal amounts if not in an open-air environment. Okay; safety talk over with.
