I have seen this question posted here and there and I have the answer for you! The best way to Mount the Torqeedo 403 Throttle Controller is using a RAM Mount. Then go to your local Hardware store and match the threads to a Stainless Steel screw and mount it to the diamond base RAM ball.  Now you have plenty of mounting options!

RAM Mounts you’ll need

RAP-B-201U Composite Double Socket Arm that will receive a 1″ ball

RAM-B-238U RAM 2.43″ x 1.31″ Diamond Ball Base with 1″ Ball

Screws needed for ball to controller mounting Metric M4-0.7 x 20mm stainless steel screws

Mounting to Kayak

RAP-B-379U-252050-KAY1  RAM 1″ Tough-Ball™ with 1/4″-20 X .50″ Male Threaded Post for Kayaks

OR

RAP-B-354U-TRA1 Track Ball^™ with T-Bolt Attachment
