Recently set up a portable transducer unit for my 998 and looking at placing the head unit on a Ram mount to make it easier to transfer between boats. Was wondering if any of you were running the Ram mount set-up using the 1.5" ball and how is it working? Am unsure if the 1.5" system will be strong enough although website says up to 10#, weighed my head unit it weighs 4#. Wanted input before buying.
