We have a 2009 350 Sundancer. Twin I/O Mercruisers 496 B3 AXIUS
The boat is typically plugged into shore power. Both motors fired up fine. We took the boat to a local harbor for dinner and decided to stay the night.
Since we didn’t have shore power that night, I thought it best to turn the batteries off at night. Next morning turned the batteries on and fired up both engines no problem.
About 30 min into our cruise we stopped the boat to take in the views about a mile offshore. As soon as the boat came to idle the starboard shut down. Tried to restart but would barely turn over seemed like the battery was dead. I turned on the generator thinking it would charge the battery.
After about 10 min the engine fired up. Then turned off the generator and decided to head back our marina. As I approached our slip and brought the rpm’s down to idle, the starboard motor died again. It wouldn't start even with the generator on this time. Btw, I’m not sure the generator even charges the engine batteries.
Needless to say, I was a mess docking with one engine.
Any thoughts on what my problem is? Hopefully it’s just a bad battery.
Thanks
Dave
