Title: Trolling motors in saltwater
Post by: Fishhunt223 on August 28, 2009, 04:18:58 PM
Has anybody ever used their freshwater trolling motors in the salt?  I heard that you have to replace a seal every time but is that the extent?  It is a minn kota auto pilot.

Electrolysis is you biggest enemy.  Salt water and electrical current hate each other and will eat away at your metal.  You need to put a sacrificial metal (zinc) on it so electrolysis will attack it instead of your trolling motor.  Also, wash the hell out of everything with soap and water when you are done.

So just put the hunk of zinc right on the bottom of my trolling motor or does it need to be touching metal?

I would say between the shaft and the prop on top.

Take a look at Mini Kota's marine versions to see the difference.

I would pick up the white Min kota trolling motor.  I used the standard one and it is dead.  I even washed it really good after each use.  The zink won't help on to much on a standard trolling motor.
