After a few weeks delay, the engine finally arrived in Welkom last week. It’s a Yanmar 4JH4AE with a ZF30M mechanical multiple plate type transmission. The 4 cylinder engine develops 54 hp (40 kW) at 3000 rpm. The gear ratio of the transmission is 2.15:1.
At the front end the big bracket and double pulley is visible. Here the Balmar 24VDC, 140A, marine alternator will be fitted. This alternator will charge the 460 Ah 24VDC house bank. The other alternator at the drive end of the engine, is the 12VDC 80A alternator for the starter battery.
