FYI to all, I have a 2020 Ranger and the 3 in 1 is mounted to the step on the hull. The new 3 in 1 HD does not have the same mounting holes in fact there are no holes. I spoke to Lowrance and there is no bracket or fix at this time to mount it back where the old one exists. I was told by a dealer flush mount bracket number 000-12602-001 will work. I ordered it prior to calling Lowrance. It has not arrived yet will update the board when it arrives. Options are to mount it to the back of the Transom or with a Jack plate bracket.
