Transmission Cooler Zincs

[navigator336]

I have twin 350 GM's attached to ZF Hurth vee-drives. The tranny coolers (simple torpedo shaped raw water heat exchangers)do not have zinc anodes (at least not that I can find). The boat is used only in salt water. It makes me nervous <br />having trans fluid running through an un-protected cooler. Any thoughts on whether I should be concerned or is there a special zinc made to mount inside this type of cooler?<br /><br />Thanks.

Don't know how your coolers are designed but you can often replace the drain plugs on the cooler with a plug that will accept a pencil zinc.
