BW 350 Outrage thruster wiring

We got a 2020 Outrage 350 as a tender for the 110 I run. Good condition, feels solid and nice layout but so far I m not impressed with the electrics. It feels like Boston Whaler hired former Mutt engineers to design the system. Apologies to our Italian friends

the boat has a 24VDC thruster with the 2 batteries installed deep in the fwd bilge along with a Pronautic charger. Also down low in the bilge which has a tiny bilge pump and no high water alarm (already remedied)

problem is that you can only charge the shore power batteries on shore power. I guess in the typical day outing scenario, it’s no big deal as you will recharge the batteries after you get back to your home slip. But when using the boat as tender back n forth to shore with a lot of docking it means having to run a shore cable at night from big boat to the little one.

doesn’t make a lot of sense to me… thinking about adding a 12-24 charger so the batteries recharge whenever the engines are running

anyone familiar with the new Victron Orion 1400 XS? 70 amp multi voltage. I would power it from the center engine / house bank (two batteries). L

I looked and haven’t found it. Not mentioned in the manual either. There ACRs near the main batteries but as far as I can see they re not for the thruster bank.

Yes 24 vdc thruster with two g31. Factory install. I m not impressed by the electrical a, for instance the AC panel has a small analog voltmeter which is pretty much useless.

i agree that a thruster is an overkill on a boat that size but I won’t be the one driving the tender much. I want to make it easy on the crew. And some docks can be crowded when we pick up Or drop off guests

when anchored in the Bahamas, we may not need to power the tender at night so I really want the thruster batteries charged while underway. Will also avoid deep discharge which shorten life.

I doubt it. Seems like adding that Victron charger is the easiest way to fix this.

The hardest part of the job will be to run wires from the 12v bank in the rear to the thruster at the bow and it will be needed in both cases.

will also need to add an ACR to charge the thruster batteries. And replace the 24v charger with a 12 volt charger …

The mystery deepens…

The boat cavity manual states the thruster is 24Vdc
The electrical panel is labeled 24VDC thruster

but… the meter for the thruster bank shows about 12v
The BlueSea remote battery switch is marked 12vdc
The two batteries are wired in parallel
The Lewmar thruster motor is marked 12VDC
The ProMariner charger is 24VDC. Needless to say it shows a fault and isn’t working.

I have no record of the electrical side of the thruster having been worked on, just the gearbox. No other thruster work in the 6 years of maintenance record

crazy.

Almost impossible to run wiring on that boat. There is a chase but it’s full and everything else is sealed.

I may just give up on charging while underway.

I talked to the previous owner yesterday, he’s looking for a missing invoice. It appears marine max replaced the whole thruster a few months ago and for whatever reason used a 12 v motor and rewired the batteries to parallel. He didn’t use the thruster much so it s possible the batteries still held some charge.

They also must have replaced the BlueSea remote battery switch from 24 to 12VDC… incredible.

I was shaking my head going thru the invoices from MarineMax… things like Vacuflush not building enough vacuum … replace the whole pump. I guess they don’t know the duckbills are replaceable. And the list goes on.
