If you just want to do it for fun then go for it but separate systems will be a pain to trouble shoot. With two yanmars you are out there before the batteries arrive from China
Again, it's a very risky thing you are doing. The scale of the system for a lagoon 560 is a challenge.
I've been quoted by a Yanmar dealer, $50,000 for 2x Yanmar 110, 2x ZF 68 IV Transmission
and 1x Control Unit. However, the lead time is currently 6 months due to a backlog in the manufacturing of the ZF transmission.
Batteries from Delong, I ordered a 2nd house battery 3 weeks ago, it arrived about 4 days go.
As yet I am undecided, currently in the information gathering phase.
I'll summise a complete solution into a single
sheet of paper, pin it to my desktop
homepage or to the wall in clear line of sight. Walk past it for few days at least to allow a period of reflection.
If I proceed at least I know, the reason(s) I choose to do so.
