On my 2003 38 Open I have 6 GEL batteries, 3 for the house & 3 for the engines which I replaced after 17 years. Prior to changing them I started to have an intermittent cranking problem with the Starboard engine.. Not all the time but several times over the season it cranked slowly but it always started... Used the parallel button and the starboard cranked much better.... Not sure if the batteries were the problem as I also changed the starboard engine ignition switch which which seems to have had an affect on the slow cranking.. After 17 years the batteries needed replacement so I believe that was the root issue although the ignition switch could have contributed to the problem... Checked all connections, power & grounds, to ensure all good. Problem gone...
