Another new AR240 owner

[W3bexec]

Hello. I have been lurking the forums for the last few months as I was researching the boat we wanted to buy. I appreciate all the helpful information here. This is our second boat and first jet boat (first was a older Bayliner). Whatever I know about the AR240 or jet boats is from this forum, jetboaters, and YouTube. I'm not sure if he posts on here but big thanks to Rob who has the Rob's Yamaha Jetboat DIY Maintenance YouTube channel. I've watched the crap out that channel, most informative and pushed me over the edge on going with the Yamaha.

Not sure if it is OK to post initial questions in Welcome Aboard but I certainly have some. The Yamaha dealer I got the boat from is mainly a motorcycle shop and just started selling boats this year. They have tried to be helpful but have given me some confusing info/advice. Hopefully the veteran boaters can help clear things up.
Looking for a true/false on things this dealer told me

- 1 battery from the 2 battery system is connected to each engine. True or False? This doesn't make sense to me since it would be counter to the idea of running a true start and house. Also, I have noticed that unless I switch start battery to "on" the connext doesn't power up. If this is the case, then what does the house battery actually power solo as everything seems to run through connext?

- From 3 different people at the dealership I was told the engine break in period is 10 hours, then someone else said 20 hours, then finally another guy 100 hours (seriously?!!!). What is it really?

- I should change oil every 20 hours. True or false?

Welcome to the forum!!! I'll give a shot at your questions:

1) Not sure how the stock set up and type of switches they are using on the AR240, but typically the engines are connected to battery 1 (start battery), and stereo is connected to battery 2 (house battery). Yes, connext won't work until battery 1 is on (it is the brain of the boat).
2) Engine break in period is 10 hours.
3) Most of us change the oil once per season. Change it more often if you are boating more than ~150 hours a season (my calculation on that is if you average 35mph, 150 hours = 5250 miles). Every 20 hours is silly.

Hi Julian, thanks for the reply and the information. Gosh, I'm glad its not really 100 hours for break in!

Welcome aboard.... And 100 hours is just silly.. Why cant sales people just say they don't know instead of filling dead air with bs?

On my 2017 AR240, connext will power up with just the house battery turned on. Break-in is not ten hours, first service is at 10 hours. Break in is more along the lines of : first 5 min below 2500, next 1/2 hr below 4000, next 1/2 hr below 6k, then you're good to go. It's in the "owner's manual", I believe.

This ^^. Here is a capture directly from the 2017 212x owners manual. Imagine the AR240 will be the same.
