Of course you do. One of the reasons your batteries are located at the stern. Your battery will not last as long mounted forward. You have to decide if its worth it for them to not last as long. So what is the reason you are moving them forward?Do I have to worry about the additional vibrations on the battery
car batteries have all kinds of vibrations and they last alright
well you need to come up here and drive on our roads. you would change your mind.Not the pounding like you get in a boat. Cars have springs and shocks, and are usually run on improved roads.
On battery selection, OTR truck batteries are build tough because those babies take a beating too.

The reason I wanted to move it forward is there is a small area in rear where battery was kept that shared the fuel line I already routed the fuel line out of there. abut its small and hard to get in there . I want to put a battery shut off switch and would be more convenient under console. So I decided to leave battery where it is and route pos wire uo to console and back and put shut off switch in console its about twelve feet and I plan on using 2 gauge
+++1Seems like there must be somewhere back by the battery that you could install the shutoff.
