replacement thruster zinks

[bridget]

Is the Zink anode used on the rear thruster the same as the one used on the front thruster? The only one on the 27 ft ranger tug part sheet is # 32948. I have read in previous posts that there is a zink from 'boatzinks.com' whose # is sm31180. Is this a correct zink to use and can it be used for both front and rear thrusters?

They are the same for front and rear. You want SM31180A. It is aluminum. Good for salt and fresh. Here is the link https://www.boatzincs.com/sm31180.html
