Picked up new AR250 and have a few question

[Gooch]

Finally got to pick up the new boat today. The dealership did a great job cleaning everything up, i couldn’t find any fiberglass dust anywhere. I do have a few questions though as my salesman was less than helpful when it came to product knowledge.

1st. Is it normal for both battery switches to be on in order for the radio to work?
2nd. He mentioned that the two red hoses than run thru the bulk head behind the engines need to be clamped off if I’m getting towed. He didn’t know why or how.
3rd. There are warning stickers all over this boat warning me that if I fall overboard or fall in the boat I may be injured. Arrgggg! Anyone know the best way to remove these?

I truly appreciate all of your help.

Congrats!

1st. Is it normal for both battery switches to be on in order for the radio to work?

On my 2020 model I only needed the House on for the radio to work, however the Connext would fire the low battery warning for the Start battery, so I need them both on. Maybe the newer Connext needs both on.

2nd. He mentioned that the two red hoses than run thru the bulk head behind the engines need to be clamped off if I’m getting towed. He didn’t know why or how.

Those are the raw water intake lines for engine cooling. If you're being towed or are running one engine, you need to clamp off the hose for the engine that is off so water isn't pushed up the hose and into the exhaust which can back-fill into the cylinders = very bad.

Tehcnically it's ok to tow at no wake speeds like 5 mph, but any faster and the pressure will build up pushing water into the engines. I recommend buying a pair of hose clamps from the local hardware store and keep them in case of emergency. You'll probably never need them, but it's a good safety measure and will save your engines from damage.

3rd. There are warning stickers all over this boat warning me that if I fall overboard or fall in the boat I may be injured. Arrgggg! Anyone know the best way to remove these?

Goo-Gone or WD40 will help remove the stickers and residue. I've removed all of them too, including inside the cockpit by the throttles and start keys.

Awesome. Thanks for the information.

Use a blow dryer for a little heat on the sticker and they will peel right off I removed all mine also except for fire extinguisher compartment ones. Congrats!

I agree, would bet the red hoses are the water source when hooked up to the hose,

You need to clamp the line that comes from intake at the jet nozzle,

We have a video in the faq section "how the cooling water flows" even though it's for an older engine it's basically the same and a must watch for new owners

On my 21 I too noticed both had to be on to power the radio. Completely defeating the purpose... Cool.

Having both switches on does not defeat the purpose of having dual batteries as long as the system is only drawing from the House battery when floating and keeping the Start battery ready to fire up the engines. On the 2021 it might just be a sensor on the Start side that triggers the Connext system to turn on. It's not hard to see if the stereo is only pulling on the House battery.

If it's relying on just a sensor... then why even have 2 switches?
It's a heck of an odd way to go about it, if nothing else.

I plan to get out there with an ammeter and see how much draw there is from each battery once it gets back above freezing and all the snow we just got melts. Hopefully later this week.

Automatic isolation and dual charging capability.

If there was only one switch, both batteries would be connected when the single switch was on draining both which could leave you stranded. Not much sense in that...might as well have just one battery.

With two switches and a DVSR, when the engines are off, only the House is being used and the Start is isolated. When the engines are running, the DVSR senses the charging voltage and connects both batteries to charge them up together. Once you shut off the engines, the DVSR cuts the connection and Start/House are isolated again. This way you should always have a charged Start battery to fire up the engines.
