I looked into the lithium batteries more, it seems they are can be unstable and actually catch fire! You’re right, not good for a boat.
Thanks

We’ve made some more progress. Boat is back at Team Archer getting a wiring redo along with new dash arrangement. All the aluminum engine mounts and other brackets have now been anodized. Sea strainers are done. Water pickups located on transom. I’ll have more pics soon for completion of dash and engine installations.

There’s no stopping now, the time and money invested...I want to enjoy it this summer. Attached are pictures of modified dash and new throttle box painted, again Dan at Archer is really doing a nice job. When dash is completed, I will attach before and after. It’s going to be pretty dramatic.

New dash sanded and polished ready for final wiring. New with the old

Here’s the before picture.

Both engines back in. Custom sized strainers and gearoil/fuel coolers in place, exhaust complete...all coming together! Fine tuning the fuel side at this time. Here’s a recent pic.
