AGM and Flooded battery combination
I recently bought a boat that has a regular 12 v battery for the 90 hp outboard eng and a Optima 12 v AGM to run a few lights. I would like to put them in the same area and combine them for recharging...

Please remember
Outboard engine charging systems are VASTLY different from Cars, Trucks and RV charging systems. They tend to be more similar to Tractor charging systems than any of the previous.
Check your battery cable connections they are major contributors to failed charging systems on outboards.
The Yamaha charging system consists of a simple 3 phase stator. The flywheel is called the rotor because it contains the rotating magnetic field. The coils feed a 3 phase sine wave A/C voltage to the rectifier/regulator. There it is rectified by a full wave bridge rectifier and fed to the regulator side what power is not used is simply shunted to ground. A simple brute force design that is prone to failure when the starting battery is disconnected.
