theoretically these things should generate 38 amps from the alternator, more than enough to charge more than one battery. does anyone have feedback on this?

The 90 HP Honda pre 2007 only put out 17 amps. The newer and higher HP put out 44 amps. I only had larger Suzuki's but they also put out in the 40 amp range--you will be fine with several batteries. Use a Voltage Sensitive Relay, if the outboard does not have a secondary charging circuit, between the engine start and house battery. On a 16 often "multipurpose batteries" are used and should be of the same type, size and age for best results.
