| if you dont want to take out the trays for 27's if that's what you already have in the boat, and install new trays for 31, you can probably modify the existing 27 trays w/o even taking them out...razor blade/exact knife/carpenter's knife.. just cut the corners on side so it opens up and the longer batteries will fit...
bigger boat, bigger trolling motor, bigger batteries for sure. |

| I would never own another boat with anything smaller than 31 series batteries. I've ran my maxxum 80lb for a good 6 hours on 100% and it still had juice at the end of the day, and this is on a 1760 tuffy. My buddy has a 185 ranger BASS BOAT with the same setup only 27 series and after about 5 hours of 100% its almost dead, and both sets of batteries were new this spring. Do yourself a favor and get the 31's, you won't regret it. |
