[C320-list] 4 D Battery Replacement

[Pete Herron]

Chris,

You may want to check out the smaller Balmar alternators.  The 120 A 
alternator has two pulleys and that would be a pain to accommodate.  
The large alternators also take a more engine power.  Maybe Yanmar 
could tell you if it is OK or too much load for your engine.

I installed a 70-80 (70 series, 80 A) alternator.  It fits well and 
works well.  If I let the batteries drop to near 12v, and run the 
engine at about 1800 rpm, I can replace an indicated 40+ Ahr in just 
one hour.  Leave the dock with batteries fully charged, run the motor 
one hour a day, and you'll have hot water and plenty of juice for a 
week.  We are power misers, don't charge until the third day, and we're 
still good for a week.
