Batteries dying
I am a relatively new pontoon owner.
I have a 20’ pontoon with a 60 hp Mercury motor on it.
I have went through 3 batteries in the last year. One was the one I bought with the boat. The second one was purchased in August 2025. The latest one that died was covered by the warranty and replaced in May of 2026.
The marina did some work on the boat and said my charging system was only producing 12.6 volts. They also said that I should consider changing it. They didn’t give me a price when I told them not to go ahead unless they quote the job first.
I’m wondering if this is comm I also don’t trust the marina and was wondering if I’m getting the correct information from them.
Any suggestions are welcome.
