I cut a hole and installed an inspection plate on the swimstep. This took very little time compared to what removing the batteries would have taken.thanks guys for the tips. i think i should have good access to the port side as i have the "pull out bin" on that side. for the starboard, i plan to remove the batteries, go down on the port side, crawl across where the batteries were and hopefully get the access i need.
i will definitely report back and let everyone know how many 4 letter words it took. it will probably be a january or february project
