Hello group,

Would someone know the alternator charging max for this engine? I looked in the owners manual but its not listed. I'm not sure if its enough to charge 3 batteries

Thanks
Arnie

We need the serial number to check which alternator it hab, rule of thumb is with a rectifier it's a 9 amp. system and with a voltage regulator it's 16.
