Anode question

[ctcruiser]

Hey Guys I feel stupid asking this boat I have a raw water cooled engine 2001 and had my manifolds replaced last year. Does the manifold have any pencils anodes I need replace?

None in any boats I've owned. Crusader and Merc. There may be an anode in the oil cooler if your engine is equipped with one.

Raw water engines aren't dedesigned for saltwater, and I don't think anodes would be on any of them. Even with anodes, the manifolds don't get the protection needed because there's no water in them when the engine is not in use (which is the vast majority of the time), and anodes must be submerged in order to work. I believe manifolds typically are replaced in say, 4-5 year cycles. There are SS manifolds on the market which offer a long life. There's no reason why you couldn't install a pencil anode on the manifold, but it wouldn't do much because of the above senerio.

I don't have one but there are many raw water cooled engines running in salt water. Just be sure thermostat is 140°F so that salt doesn't crystallize from salt water.
