Thanks for the channel and the info. You’re both a pleasure to watch and the info has been hugely helpful. We’re taking deliver of our 895 tomorrow!! Greetings from Dublin, Irl! Rob
I had a similar problem with my 1095. I had it pulled out for a service, and must have forgot to turn the house batteries off. I have two large Lithium batteries for the house, and two starter batteries for the engines. It had been out of the water for a week, and when it was put back in the water, everything was flat, the house batteries and the starter batteries. There was no lights on the dash, no sounder and none of the battery lights illuminated when I switched them on. You couldn't even hear the solenoids clicking. Everything was dead. One of the guys working at the marina tried to jump start the motors with a spare battery that he had, but there was still nothing. The only thing I could get going was the generator which has an isolated battery. When the generator started, the battery charger started, and although the lights and sounder worked, none of the other electronics worked. The battery switches still didn't work. After an hour there must have been enough charge in the starter batteries, for the battery switches to work. The lights on the switches came on, but I couldn't start the engines, until I used the fob to unlock the ignition for both engines. After that the electronics came up, and the engines started. I personally think that it must be a Yamaha default setting, to lock the ignition if the power is cut to the batteries. It drove me nuts, I was nowhere near as calm about it as you. Well done for being able to get it home. At least you didn't have to call VMR.
Aren't batteries the best!! So another lock-out with low batteries. The weird thing is mine de-immobilised by doing nothing. I definitely didn't hit the immobiliser button. Anyway, thanks for sharing. Guess I'm going battery shopping.
Still no real answer. Current theory is strange voltage pattern must have triggered the immobiliser. I guess make sure you have the key fob with you!!!
Not on our Jeanneau, but on our last boat we had to limp home at 4-5 knots. That boat only had one engine but it would scream at us if we went over a certain RPM because of a clogged pipe or something. Let's just say as beautiful as the Manhattan skyline is via boat, when you are passing it for three hours to get back to your marina it gets a bit old. I guess there are much worse problems though. LOL. I am just glad it was a bigger issue for you guys. Boating is ALWAYS an adventure right?
Yes We had a few limps home in our last boat, hence the reason it had to go. Just so unreliable. One reason I do love having two engines. I find not many people want to listen to you complain about your 30' motor boat :)
Batteries, batteries and batteries. The electronics relay on correct voltages to function correctly. If you suspect the issue is to do with low voltage (below 11.5v), cut all load and let the solar charge up for at least 2 hrs. had myself stranded in the bush due to a dead start battery. Solar blanket saved the day.
Batteries are the cause of so much mis-adventure. I believe you are correct for some season the low voltage triggered the immobilser, although no one has heard of this before. Guess I'm doing some battery shopping now.
Very glad we have a starter battery that can be completely isolated so never have a problem starting just the mystery of why the engine was immobilsed after the low voltage.
Hi Damien & Brooke. Certainly a different video to post. Amazed that you had this problem, given that you have fitted a huge leisure battery! Plus you have solar. Why was there such a big drain on your battery. As I know you have a Victron battery monitor and keep a check on things ( as per one of your previous videos). Could it just be that ( in some way) the key fob activated the immobilisation as it went flat? Seems strange that only one engine was immobilised. Look forward to learning why it happened so we can all be aware of this fault/problem. You certainly did the right thing. Just get home safe. Then you relax, recover and have lots of time to sort things out. Sorry to see you both so knackered. Please post as soon as you have the answer. Best regards to you both.
Everything is still a mystery! Even the battery going dead. I just did a test at home running the boat on battery with the fridges on etc. I think there is something wrong with the battery. It lasted for a day very well and then after using 60aH the voltage started to drop again. I have a feeling that the AGM battery has been damaged due to the fact that it has to crank the port side engine. Looks like I'm shopping for a battery :( The dealers have no idea why this would trigger the immobilser. Anyway home safe. cheers
@@TheRudder Thanks for thé update Damien. Appreciated. It does seem strange that the immobiliser activated? I wonder if Yamaha can answer that one. If, as you say, it was caused by the large leisure battery then I hope the manufactures will help provide a new one. Boats, like cars, often present mechanical problems/challenges but it is always good/reassuring to know what caused them to prevent them happening again. Please let me know if you find out anymore. Best regards and smooth sailings to you both.
Perhaps I missed it: Why 'limping' on the remaining engine vs. higher rpms? Re:" the issue", sounds like you had a telltale sign the previous evening. If that big house bank voltage is plummeting but the amp/hr count doesn't correspond, a circuit is obviously pulling amps off the house bank but is outside the BM shunt's connection to the negative side of the house bank.
Hi Jack, I think the battery is damaged rather than a phantom current. Still doesn't explain the immobilsation of the engine. I guess were weren't in limp mode like inboard engines. just going slow on one engine. Cheers
Hello. I sometimes didn’t see that the gas handle was slightly engaged (a few millimeters). Security then prevents starting and the light does not turn on. Have a good day.
Some cells could be damaged in your battery, and really low voltages can cause strange things, probably that was something that triggered yamaha Y-COP. I've learned from you to have spare batterys for that key fob! Do you have a more advanced battery tester on hand? It can tell it's internal resistance and estimated capacity. Glad you made it home safe. Was the boat ok to steer with just one engine running? :s
Thanks, yes I think the battery is damaged in some way. Problem now is getting it out for testing, I don't have any better testing equipment on hand. Thing weighs 80kg!! All safe, no damage done.
Sounds like a defective battery to me. A warped plate or otherwise damaged cell. If the BM shows a decent SOT but the voltage is low…. Your battery is probably toast.
I fear so as well. They want me to test the battery. Not so easy when the thing weighs 75kg and getting it out is going to be a complex and difficult task.
Limping home on the starboard engine was the right call Capt… all of our electronics are great when they are working !
Cheers Rick, always good to get home after an 'adventure'

Wow how exciting!!! Thanks for reaching out, I hope your first voyage goes well and you have great weather!

Thank you for sharing. One more thing to worry about before leaving the dock. Look forward to learning the answer.

"Have ya tried turning it off and on again?" Just kidding - Glad ya made it and glad you figured it out.
Hahaha too soon 😂 but yes that would have worked.
Thank you for sharing this experience with us.
Thank Brooke, I really wasn't in the mood to film anything!

Glad you made it back safely , i always carry onboard a battery jump start kit. It's as big as a mobile phone and can start a flat battery.

I have been Googling about the Yamaha Immobiliser system. Lots of interesting details

Yes have definately had that problem but you can see on the motor control unit the immobilised symbol.
