I have finally pulled the trigger and my new Helix units will arrive in the next few days. I have been gathering stuff to make the install as quick and painless as possible. I do, however, have one question. I'll be upgrading from a 898 to the Helix 10. I know that the transducers are different (the Helix transducer will be larger) but can I mount the transducer in the same location on the transom? Another option would be to tie into the jack plate with a longer bolt. I figured since the holes are already there for the transducer that's mounted, why mount the new transducer anywhere else?
