I use a Troll-a-Matic........It is automatic.....most of the others you have to pull a cable to engage or disingage them. The Troll-a-Matic allows my 115 Yamaha fourstroke to troll as slow as 1.5 mph Cabellas has the Troll- a- Matic but it is not in their catalog but you can go on line to Cabelas then type in Troll-a-Matic trolling plate in their search box and you can bring it up. What is good about it is....you don't have to remember to pull the cable before you take off fast....failure to do so you will tear your trolling plate up. You can also get them here...... http://www.franksgreatoutdoors.com/trol-a-matic-1.html
