Sale!
Original price was: $1,189.00.$899.00Current price is: $899.00.
For the cruiser who requires optimum charging with their Yanmar JH-CR Series engines, we have produced this state of the art compact system that allows for dual alternator installation in most engine bays for a variety JH-CR Series engines. See below for specific engine models
This clever design allows you to run twin alternators to substantially reduce your charging time.
Boat owners are now no longer limited to just upgrading their old alternator to a 100 amp alternator on a single V pulley, with this kit you can now increase your output up to 250 amps each if required… That’s right, 500 amps from your engine!
***This kit is not compatible with the 4JH3 Series of engines an. Please contact us to confirm fitment prior to ordering.
(Note: This item is only compatible with our Serpentine Pulley Upgrade Kit systems, while shown here with our self tensioning kit, a self tensioning kit is not necessarily required. Also, the way the engine is mounted in the vessel may interfere with clearance required to run a second alternator)
