Hi... I have 2000 Mainship 390.. Went thru the same thing.. Found that, the best solution was to change over to 4-GC-2 Golf Cart Batteries ( same total amp/hr as the old, heavy 8D's), forget the boxes & use 8- Nylon, battery straps, screwed to the plywood tray. Now can get to the individual...

Yes, Unfortunately this was a problem with early 350/390's & the Factory tried to stonewall it for years. Your engine & the 3126 CATS, were the big problem. Mainship blamed CAT, CAT blamed Mainship. They were BOTH at fault When Mainship was forced to change over from the 3116 to the 3126 CATs...
