Ultimate charging upgrade for an Isuzu 42 with standard V pulleys. 120 amp domestic and 90 amp start alternators with custom pulleys/quadpower belts twinned with Victron Cyrix combiner. ***As of April 2020 I now have a 175A Poly V with Freewheeling pulley drive available for these Isuzu engines.***
1300 watt Candy 100f fitted from new but the original 70amp alternator doesn’t keep up at any engine speed and batteries take a hammering which always happens on the Aqualine boats of this era.
Now generates 1.1kw at 800rpm tickover and excess power just off tickover.
